[ Subscribe to RSS ](https://developers.cloudflare.com/changelog/rss/index.xml) [ View RSS feeds ](https://developers.cloudflare.com/fundamentals/new-features/available-rss-feeds/) Storage ![hero image](https://developers.cloudflare.com/_astro/hero.CVYJHPAd_26AMqX.svg) Aug 19, 2025 1. ### [Subscribe to events from Cloudflare services with Queues](https://developers.cloudflare.com/changelog/post/2025-08-19-event-subscriptions/) [ Queues ](https://developers.cloudflare.com/queues/) You can now subscribe to events from other Cloudflare services (for example, [Workers KV](https://developers.cloudflare.com/kv/), [Workers AI](https://developers.cloudflare.com/workers-ai), [Workers](https://developers.cloudflare.com/workers)) and consume those events via [Queues](https://developers.cloudflare.com/queues/), allowing you to build custom workflows, integrations, and logic in response to account activity. ![Event subscriptions architecture](https://developers.cloudflare.com/_astro/queues-event-subscriptions.3aVidnXJ_Z2p3fRA.webp) Event subscriptions allow you to receive messages when events occur across your Cloudflare account. Cloudflare products can publish structured events to a queue, which you can then consume with [Workers](https://developers.cloudflare.com/workers/) or [pull via HTTP from anywhere](https://developers.cloudflare.com/queues/configuration/pull-consumers/). To create a subscription, use the dashboard or [Wrangler](https://developers.cloudflare.com/workers/wrangler/commands/queues/#queues-subscription-create): Terminal window ``` npx wrangler queues subscription create my-queue --source r2 --events bucket.created ``` An event is a structured record of something happening in your Cloudflare account – like a Workers AI batch request being queued, a Worker build completing, or an R2 bucket being created. Events follow a consistent structure: Example R2 bucket created event ``` { "type": "cf.r2.bucket.created", "source": { "type": "r2" }, "payload": { "name": "my-bucket", "location": "WNAM" }, "metadata": { "accountId": "f9f79265f388666de8122cfb508d7776", "eventTimestamp": "2025-07-28T10:30:00Z" } } ``` Current [event sources](https://developers.cloudflare.com/queues/event-subscriptions/events-schemas/) include [R2](https://developers.cloudflare.com/r2/), [Workers KV](https://developers.cloudflare.com/kv/), [Workers AI](https://developers.cloudflare.com/workers-ai/), [Workers Builds](https://developers.cloudflare.com/workers/ci-cd/builds/), [Vectorize](https://developers.cloudflare.com/vectorize/), [Super Slurper](https://developers.cloudflare.com/r2/data-migration/super-slurper/), and [Workflows](https://developers.cloudflare.com/workflows/). More sources and events are on the way. For more information on event subscriptions, available events, and how to get started, refer to our [documentation](https://developers.cloudflare.com/queues/event-subscriptions/). Jul 03, 2025 1. ### [Hyperdrive now supports configuring the amount of database connections](https://developers.cloudflare.com/changelog/post/2025-07-02-hyperdrive-configurable-connection-count/) [ Hyperdrive ](https://developers.cloudflare.com/hyperdrive/) You can now specify the number of connections your Hyperdrive configuration uses to connect to your origin database. All configurations have a minimum of 5 connections. The maximum connection count for a Hyperdrive configuration depends on the [Hyperdrive limits of your Workers plan](https://developers.cloudflare.com/hyperdrive/platform/limits/). This feature allows you to right-size your connection pool based on your database capacity and application requirements. You can configure connection counts through the Cloudflare dashboard or API. Refer to the [Hyperdrive configuration documentation](https://developers.cloudflare.com/hyperdrive/concepts/connection-pooling/) for more information. Jun 25, 2025 1. ### [@cloudflare/actors library - SDK for Durable Objects in beta](https://developers.cloudflare.com/changelog/post/2025-06-25-actors-package-alpha/) [ Durable Objects ](https://developers.cloudflare.com/durable-objects/)[ Workers ](https://developers.cloudflare.com/workers/) The new [@cloudflare/actors ↗](https://www.npmjs.com/package/@cloudflare/actors) library is now in beta! The `@cloudflare/actors` library is a new SDK for Durable Objects and provides a powerful set of abstractions for building real-time, interactive, and multiplayer applications on top of Durable Objects. With beta usage and feedback, `@cloudflare/actors` will become the recommended way to build on Durable Objects and draws upon Cloudflare's experience building products/features on Durable Objects. The name "actors" originates from the [actor programming model](https://developers.cloudflare.com/durable-objects/concepts/what-are-durable-objects/#actor-programming-model), which closely ties to how Durable Objects are modelled. The `@cloudflare/actors` library includes: * Storage helpers for querying embeddeded, per-object SQLite storage * Storage helpers for managing SQL schema migrations * Alarm helpers for scheduling multiple alarms provided a date, delay in seconds, or cron expression * `Actor` class for using Durable Objects with a defined pattern * Durable Objects [Workers API ↗](https://developers.cloudflare.com/durable-objects/api/base/) is always available for your application as needed Storage and alarm helper methods can be combined with [any Javascript class ↗](https://github.com/cloudflare/actors?tab=readme-ov-file#storage--alarms-with-durableobject-class) that defines your Durable Object, i.e, ones that extend `DurableObject` including the `Actor` class. JavaScript ``` import { Storage } from "@cloudflare/actors/storage"; export class ChatRoom extends DurableObject { storage: Storage; constructor(ctx: DurableObjectState, env: Env) { super(ctx, env) this.storage = new Storage(ctx.storage); this.storage.migrations = [{ idMonotonicInc: 1, description: "Create users table", sql: "CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY)" }] } async fetch(request: Request): Promise { // Run migrations before executing SQL query await this.storage.runMigrations(); // Query with SQL template let userId = new URL(request.url).searchParams.get("userId"); const query = this.storage.sql`SELECT * FROM users WHERE id = ${userId};` return new Response(`${JSON.stringify(query)}`); } } ``` `@cloudflare/actors` library introduces the `Actor` class pattern. `Actor` lets you access Durable Objects without writing the Worker that communicates with your Durable Object (the Worker is created for you). By default, requests are routed to a Durable Object named "default". JavaScript ``` export class MyActor extends Actor { async fetch(request: Request): Promise { return new Response('Hello, World!') } } export default handler(MyActor); ``` You can [route](https://developers.cloudflare.com/durable-objects/get-started/#3-instantiate-and-communicate-with-a-durable-object) to different Durable Objects by name within your `Actor` class using [nameFromRequest ↗](https://github.com/cloudflare/actors?tab=readme-ov-file#actor-with-custom-name). JavaScript ``` export class MyActor extends Actor { static nameFromRequest(request: Request): string { let url = new URL(request.url); return url.searchParams.get("userId") ?? "foo"; } async fetch(request: Request): Promise { return new Response(`Actor identifier (Durable Object name): ${this.identifier}`); } } export default handler(MyActor); ``` For more examples, check out the library [README ↗](https://github.com/cloudflare/actors?tab=readme-ov-file#getting-started). `@cloudflare/actors` library is a place for more helpers and built-in patterns, like retry handling and Websocket-based applications, to reduce development overhead for common Durable Objects functionality. Please share feedback and what more you would like to see on our [Discord channel ↗](https://discord.com/channels/595317990191398933/773219443911819284). Jun 19, 2025 1. ### [Automate Worker deployments with a simplified SDK and more reliable Terraform provider](https://developers.cloudflare.com/changelog/post/2025-06-17-workers-terraform-sdk-api-fixes/) [ D1 ](https://developers.cloudflare.com/d1/)[ Workers ](https://developers.cloudflare.com/workers/)[ Workers for Platforms ](https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/) #### Simplified Worker Deployments with our SDKs We've simplified the programmatic deployment of Workers via our [Cloudflare SDKs](https://developers.cloudflare.com/fundamentals/api/reference/sdks/). This update abstracts away the low-level complexities of the `multipart/form-data` upload process, allowing you to focus on your code while we handle the deployment mechanics. This new interface is available in: * [cloudflare-typescript ↗](https://github.com/cloudflare/cloudflare-typescript) (4.4.1) * [cloudflare-python ↗](https://github.com/cloudflare/cloudflare-python) (4.3.1) For complete examples, see our guide on [programmatic Worker deployments](https://developers.cloudflare.com/workers/platform/infrastructure-as-code). #### The Old way: Manual API calls Previously, deploying a Worker programmatically required manually constructing a `multipart/form-data` HTTP request, packaging your code and a separate `metadata.json` file. This was more complicated and verbose, and prone to formatting errors. For example, here's how you would upload a Worker script previously with cURL: Terminal window ``` curl https://api.cloudflare.com/client/v4/accounts//workers/scripts/my-hello-world-script \ -X PUT \ -H 'Authorization: Bearer ' \ -F 'metadata={ "main_module": "my-hello-world-script.mjs", "bindings": [ { "type": "plain_text", "name": "MESSAGE", "text": "Hello World!" } ], "compatibility_date": "$today" };type=application/json' \ -F 'my-hello-world-script.mjs=@-;filename=my-hello-world-script.mjs;type=application/javascript+module' </queues//messages" \ -X POST \ -H 'Authorization: Bearer ' \ --data '{ "body": { "greeting": "hello", "timestamp": "2025-07-24T12:00:00Z"} }' ``` You can also use our [SDKs](https://developers.cloudflare.com/fundamentals/api/reference/sdks/) for TypeScript, Python, and Go. To get started with HTTP publishing, check out our [step-by-step example](https://developers.cloudflare.com/queues/examples/publish-to-a-queue-via-http/) and the full API documentation in our [API reference](https://developers.cloudflare.com/api/resources/queues/subresources/messages/methods/push/). May 01, 2025 1. ### [R2 Dashboard experience gets new updates](https://developers.cloudflare.com/changelog/post/2025-05-01-r2-dashboard-updates/) [ R2 ](https://developers.cloudflare.com/r2/) We're excited to announce several improvements to the [Cloudflare R2](https://developers.cloudflare.com/r2/) dashboard experience that make managing your object storage easier and more intuitive: ![Cloudflare R2 Dashboard](https://developers.cloudflare.com/_astro/r2-dashboard-updates.B7WXxzMk_Z2vfGut.webp) #### All-new settings page We've redesigned the bucket settings page, giving you a centralized location to manage all your bucket configurations in one place. #### Improved navigation and sharing * Deeplink support for prefix directories: Navigate through your bucket hierarchy without losing your state. Your browser's back button now works as expected, and you can share direct links to specific prefix directories with teammates. * Objects as clickable links: Objects are now proper links that you can copy or `CMD + Click` to open in a new tab. #### Clearer public access controls * Renamed "r2.dev domain" to "Public Development URL" for better clarity when exposing bucket contents for non-production workloads. * Public Access status now clearly displays "Enabled" when your bucket is exposed to the internet (via Public Development URL or Custom Domains). We've also made numerous other usability improvements across the board to make your R2 experience smoother and more productive. Apr 17, 2025 1. ### [Increased limits for Queues pull consumers](https://developers.cloudflare.com/changelog/post/2025-04-17-pull-consumer-limits/) [ Queues ](https://developers.cloudflare.com/queues/) [Queues pull consumers](https://developers.cloudflare.com/queues/configuration/pull-consumers/) can now pull and acknowledge up to **5,000 messages / second per queue**. Previously, pull consumers were rate limited to 1,200 requests / 5 minutes, aggregated across all queues. Pull consumers allow you to consume messages over HTTP from any environment—including outside of [Cloudflare Workers](https://developers.cloudflare.com/workers). They’re also useful when you need fine-grained control over how quickly messages are consumed. To setup a new queue with a pull based consumer using [Wrangler](https://developers.cloudflare.com/workers/wrangler/), run: Create a queue with a pull based consumer ``` npx wrangler queues create my-queue npx wrangler queues consumer http add my-queue ``` You can also configure a pull consumer using the [REST API](https://developers.cloudflare.com/api/resources/queues/subresources/consumers/methods/create/) or the Queues dashboard. Once configured, you can pull messages from the queue using any HTTP client. You'll need a [Cloudflare API Token](https://developers.cloudflare.com/fundamentals/api/get-started/create-token/) with `queues_read` and `queues_write` permissions. For example: Pull messages from a queue ``` curl "https://api.cloudflare.com/client/v4/accounts/${CF_ACCOUNT_ID}/queues/${QUEUE_ID}/messages/pull" \ --header "Authorization: Bearer ${API_TOKEN}" \ --header "Content-Type: application/json" \ --data '{ "visibility_timeout": 10000, "batch_size": 2 }' ``` To learn more about how to acknowledge messages, pull batches at once, and setup multiple consumers, refer to the [pull consumer documentation](https://developers.cloudflare.com/queues/configuration/pull-consumers). As always, Queues doesn't charge for data egress. Pull operations continue to be billed at the [existing rate](https://developers.cloudflare.com/queues/platform/pricing), of $0.40 / million operations. The increased limits are available now, on all new and existing queues. If you're new to Queues, [get started with the Cloudflare Queues guide](https://developers.cloudflare.com/queues/get-started). Apr 17, 2025 1. ### [Read multiple keys from Workers KV with bulk reads](https://developers.cloudflare.com/changelog/post/2025-04-10-kv-bulk-reads/) [ KV ](https://developers.cloudflare.com/kv/) You can now retrieve up to 100 keys in a single bulk read request made to Workers KV using the binding. This makes it easier to request multiple KV pairs within a single Worker invocation. Retrieving many key-value pairs using the bulk read operation is more performant than making individual requests since bulk read operations are not affected by [Workers simultaneous connection limits](https://developers.cloudflare.com/workers/platform/limits/#simultaneous-open-connections). JavaScript ``` // Read single key const key = "key-a"; const value = await env.NAMESPACE.get(key); // Read multiple keys const keys = ["key-a", "key-b", "key-c", ...] // up to 100 keys const values : Map = await env.NAMESPACE.get(keys); // Print the value of "key-a" to the console. console.log(`The first key is ${values.get("key-a")}.`) ``` Consult the [Workers KV Read key-value pairs API](https://developers.cloudflare.com/kv/api/read-key-value-pairs/) for full details on Workers KV's new bulk reads support. Apr 10, 2025 1. ### [D1 Read Replication Public Beta](https://developers.cloudflare.com/changelog/post/2025-04-10-d1-read-replication-beta/) [ D1 ](https://developers.cloudflare.com/d1/)[ Workers ](https://developers.cloudflare.com/workers/) D1 read replication is available in public beta to help lower average latency and increase overall throughput for read-heavy applications like e-commerce websites or content management tools. Workers can leverage read-only database copies, called read replicas, by using D1 [Sessions API](https://developers.cloudflare.com/d1/best-practices/read-replication). A session encapsulates all the queries from one logical session for your application. For example, a session may correspond to all queries coming from a particular web browser session. With Sessions API, D1 queries in a session are guaranteed to be [sequentially consistent](https://developers.cloudflare.com/d1/best-practices/read-replication/#replica-lag-and-consistency-model) to avoid data consistency pitfalls. D1 [bookmarks](https://developers.cloudflare.com/d1/reference/time-travel/#bookmarks) can be used from a previous session to ensure logical consistency between sessions. TypeScript ``` // retrieve bookmark from previous session stored in HTTP header const bookmark = request.headers.get("x-d1-bookmark") ?? "first-unconstrained"; const session = env.DB.withSession(bookmark); const result = await session .prepare(`SELECT * FROM Customers WHERE CompanyName = 'Bs Beverages'`) .run(); // store bookmark for a future session response.headers.set("x-d1-bookmark", session.getBookmark() ?? ""); ``` Read replicas are automatically created by Cloudflare (currently one in each supported [D1 region](https://developers.cloudflare.com/d1/best-practices/read-replication/#read-replica-locations)), are active/inactive based on query traffic, and are transparently routed to by Cloudflare at no additional cost. To checkout D1 read replication, deploy the following Worker code using Sessions API, which will prompt you to create a D1 database and enable read replication on said database. [![Deploy to Cloudflare](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/templates/tree/main/d1-starter-sessions-api) To learn more about how read replication was implemented, go to our [blog post ↗](https://blog.cloudflare.com/d1-read-replication-beta). Apr 10, 2025 1. ### [Cloudflare Pipelines now available in beta](https://developers.cloudflare.com/changelog/post/2025-04-10-launching-pipelines/) [ Pipelines ](https://developers.cloudflare.com/pipelines/)[ R2 ](https://developers.cloudflare.com/r2/)[ Workers ](https://developers.cloudflare.com/workers/) [Cloudflare Pipelines](https://developers.cloudflare.com/pipelines) is now available in beta, to all users with a [Workers Paid](https://developers.cloudflare.com/workers/platform/pricing) plan. Pipelines let you ingest high volumes of real time data, without managing the underlying infrastructure. A single pipeline can ingest up to 100 MB of data per second, via HTTP or from a [Worker](https://developers.cloudflare.com/workers). Ingested data is automatically batched, written to output files, and delivered to an [R2 bucket](https://developers.cloudflare.com/r2) in your account. You can use Pipelines to build a data lake of clickstream data, or to store events from a Worker. Create your first pipeline with a single command: Create a pipeline ``` $ npx wrangler@latest pipelines create my-clickstream-pipeline --r2-bucket my-bucket 🌀 Authorizing R2 bucket "my-bucket" 🌀 Creating pipeline named "my-clickstream-pipeline" ✅ Successfully created pipeline my-clickstream-pipeline Id: 0e00c5ff09b34d018152af98d06f5a1xvc Name: my-clickstream-pipeline Sources: HTTP: Endpoint: https://0e00c5ff09b34d018152af98d06f5a1xvc.pipelines.cloudflare.com/ Authentication: off Format: JSON Worker: Format: JSON Destination: Type: R2 Bucket: my-bucket Format: newline-delimited JSON Compression: GZIP Batch hints: Max bytes: 100 MB Max duration: 300 seconds Max records: 100,000 🎉 You can now send data to your pipeline! Send data to your pipeline's HTTP endpoint: curl "https://0e00c5ff09b34d018152af98d06f5a1xvc.pipelines.cloudflare.com/" -d '[{ ...JSON_DATA... }]' To send data to your pipeline from a Worker, add the following configuration to your config file: { "pipelines": [ { "pipeline": "my-clickstream-pipeline", "binding": "PIPELINE" } ] } ``` Head over to our [getting started guide](https://developers.cloudflare.com/pipelines/getting-started) for an in-depth tutorial to building with Pipelines. Apr 10, 2025 1. ### [R2 Data Catalog is a managed Apache Iceberg data catalog built directly into R2 buckets](https://developers.cloudflare.com/changelog/post/2025-04-10-r2-data-catalog-beta/) [ R2 ](https://developers.cloudflare.com/r2/) Today, we're launching [R2 Data Catalog](https://developers.cloudflare.com/r2/data-catalog/) in open beta, a managed Apache Iceberg catalog built directly into your [Cloudflare R2](https://developers.cloudflare.com/r2/) bucket. If you're not already familiar with it, [Apache Iceberg ↗](https://iceberg.apache.org/) is an open table format designed to handle large-scale analytics datasets stored in object storage, offering ACID transactions and schema evolution. R2 Data Catalog exposes a standard Iceberg REST catalog interface, so you can connect engines like [Spark](https://developers.cloudflare.com/r2/data-catalog/config-examples/spark-scala/), [Snowflake](https://developers.cloudflare.com/r2/data-catalog/config-examples/snowflake/), and [PyIceberg](https://developers.cloudflare.com/r2/data-catalog/config-examples/pyiceberg/) to start querying your tables using the tools you already know. To enable a data catalog on your R2 bucket, find **R2 Data Catalog** in your buckets settings in the dashboard, or run: Terminal window ``` npx wrangler r2 bucket catalog enable my-bucket ``` And that's it. You'll get a catalog URI and warehouse you can plug into your favorite Iceberg engines. Visit our [getting started guide](https://developers.cloudflare.com/r2/data-catalog/get-started/) for step-by-step instructions on enabling R2 Data Catalog, creating tables, and running your first queries. Apr 09, 2025 1. ### [Hyperdrive now supports custom TLS/SSL certificates](https://developers.cloudflare.com/changelog/post/2025-04-09-hyperdrive-custom-certificate-support/) [ Hyperdrive ](https://developers.cloudflare.com/hyperdrive/) Hyperdrive now supports more SSL/TLS security options for your database connections: * Configure Hyperdrive to verify server certificates with `verify-ca` or `verify-full` SSL modes and protect against man-in-the-middle attacks * Configure Hyperdrive to provide client certificates to the database server to authenticate itself (mTLS) for stronger security beyond username and password Use the new `wrangler cert` commands to create certificate authority (CA) certificate bundles or client certificate pairs: Terminal window ``` # Create CA certificate bundle npx wrangler cert upload certificate-authority --ca-cert your-ca-cert.pem --name your-custom-ca-name # Create client certificate pair npx wrangler cert upload mtls-certificate --cert client-cert.pem --key client-key.pem --name your-client-cert-name ``` Then create a Hyperdrive configuration with the certificates and desired SSL mode: Terminal window ``` npx wrangler hyperdrive create your-hyperdrive-config \ --connection-string="postgres://user:password@hostname:port/database" \ --ca-certificate-id \ --mtls-certificate-id --sslmode verify-full ``` Learn more about [configuring SSL/TLS certificates for Hyperdrive](https://developers.cloudflare.com/hyperdrive/configuration/tls-ssl-certificates-for-hyperdrive/) to enhance your database security posture. Apr 08, 2025 1. ### [Hyperdrive Free plan makes fast, global database access available to all](https://developers.cloudflare.com/changelog/post/2025-04-08-hyperdrive-free-plan/) [ Hyperdrive ](https://developers.cloudflare.com/hyperdrive/) Hyperdrive is now available on the Free plan of Cloudflare Workers, enabling you to build Workers that connect to PostgreSQL or MySQL databases without compromise.

Durable Objects let you build stateful, serverless applications with millions of tiny coordination instances that run your application code alongside (in the same thread!) your durable storage. Each Durable Object can access its own SQLite database through a [Storage API](https://developers.cloudflare.com/durable-objects/best-practices/access-durable-objects-storage/). A Durable Object class is defined in a Worker script encapsulating the Durable Object's behavior when accessed from a Worker. To try the code below, click the button: [![Deploy to Cloudflare](https://deploy.workers.cloudflare.com/button)](https://deploy.workers.cloudflare.com/?url=https://github.com/cloudflare/templates/tree/main/hello-world-do-template) JavaScript ``` import { DurableObject } from "cloudflare:workers"; // Durable Object export class MyDurableObject extends DurableObject { ... async sayHello(name) { return `Hello, ${name}!`; } } // Worker export default { async fetch(request, env) { // Every unique ID refers to an individual instance of the Durable Object class const id = env.MY_DURABLE_OBJECT.idFromName("foo"); // A stub is a client used to invoke methods on the Durable Object const stub = env.MY_DURABLE_OBJECT.get(id); // Methods on the Durable Object are invoked via the stub const response = await stub.sayHello("world"); return response; }, }; ``` Free plan [limits](https://developers.cloudflare.com/durable-objects/platform/pricing/) apply to Durable Objects compute and storage usage. Limits allow developers to build real-world applications, with every Worker request able to call a Durable Object on the free plan. For more information, checkout: * [Documentation](https://developers.cloudflare.com/durable-objects/concepts/what-are-durable-objects/) * [Zero-latency SQLite storage in every Durable Object blog ↗](https://blog.cloudflare.com/sqlite-in-durable-objects/) Apr 07, 2025 1. ### [SQLite in Durable Objects GA with 10GB storage per object](https://developers.cloudflare.com/changelog/post/2025-04-07-sqlite-in-durable-objects-ga/) [ Durable Objects ](https://developers.cloudflare.com/durable-objects/)[ Workers ](https://developers.cloudflare.com/workers/) SQLite in Durable Objects is now generally available (GA) with 10GB SQLite database per Durable Object. Since the [public beta ↗](https://blog.cloudflare.com/sqlite-in-durable-objects/) in September 2024, we've added feature parity and robustness for the SQLite storage backend compared to the preexisting key-value (KV) storage backend for Durable Objects. SQLite-backed Durable Objects are recommended for all new Durable Object classes, using `new_sqlite_classes` [Wrangler configuration](https://developers.cloudflare.com/durable-objects/best-practices/access-durable-objects-storage/#create-sqlite-backed-durable-object-class). Only SQLite-backed Durable Objects have access to Storage API's [SQL](https://developers.cloudflare.com/durable-objects/api/sqlite-storage-api/#sql-api) and [point-in-time recovery](https://developers.cloudflare.com/durable-objects/api/sqlite-storage-api/#pitr-point-in-time-recovery-api) methods, which provide relational data modeling, SQL querying, and better data management. JavaScript ``` export class MyDurableObject extends DurableObject { sql: SqlStorage constructor(ctx: DurableObjectState, env: Env) { super(ctx, env); this.sql = ctx.storage.sql; } async sayHello() { let result = this.sql .exec("SELECT 'Hello, World!' AS greeting") .one(); return result.greeting; } } ``` KV-backed Durable Objects remain for backwards compatibility, and a migration path from key-value storage to SQL storage for existing Durable Object classes will be offered in the future.

These operations can be useful when: * Your consumer has a bug or downtime, and you want to temporarily stop messages from being processed while you fix the bug * You have pushed invalid messages to a queue due to a code change during development, and you want to clean up the backlog * Your queue has a backlog that is stale and you want to clean it up to allow new messages to be consumed To pause a queue using [Wrangler](https://developers.cloudflare.com/workers/wrangler/), run the `pause-delivery` command. Paused queues continue to receive messages. And you can easily unpause a queue using the `resume-delivery` command. Pause and resume a queue ``` $ wrangler queues pause-delivery my-queue Pausing message delivery for queue my-queue. Paused message delivery for queue my-queue. $ wrangler queues resume-delivery my-queue Resuming message delivery for queue my-queue. Resumed message delivery for queue my-queue. ``` Purging a queue permanently deletes all messages in the queue. Unlike pausing, purging is an irreversible operation: Purge a queue ``` $ wrangler queues purge my-queue ✔ This operation will permanently delete all the messages in queue my-queue. Type my-queue to proceed. … my-queue Purged queue 'my-queue' ``` You can also do these operations using the [Queues REST API](https://developers.cloudflare.com/api/resources/queues/), or the dashboard page for a queue. ![Pause and purge using the dashboard](https://developers.cloudflare.com/_astro/pause-purge.SQ7B3RCF_2dqU5K.webp) This feature is available on all new and existing queues. Head over to the [pause and purge documentation](https://developers.cloudflare.com/queues/configuration/pause-purge) to learn more. And if you haven't used Cloudflare Queues before, [get started with the Cloudflare Queues guide](https://developers.cloudflare.com/queues/get-started).

This means that your uncached queries and new database connections have up to 90% less latency as measured from connection pools. ![Hyperdrive query latency decreases by 90% during Hyperdrive's gradual rollout of regional pooling.](https://developers.cloudflare.com/_astro/hyperdrive-regional-pooling-query-latency-improvement.Bzz_xvHZ_rlYbl.webp) By improving placement of Hyperdrive database connection pools, Workers' Smart Placement is now more effective when used with Hyperdrive, ensuring that your Worker can be placed as close to your database as possible. With this update, Hyperdrive also uses [Cloudflare's standard IP address ranges ↗](https://www.cloudflare.com/ips/) to connect to your database. This enables you to configure the firewall policies (IP access control lists) of your database to only allow access from Cloudflare and Hyperdrive. Refer to [documentation on how Hyperdrive makes connecting to regional databases from Cloudflare Workers fast](https://developers.cloudflare.com/hyperdrive/concepts/how-hyperdrive-works/). This improvement is enabled on all Hyperdrive configurations.

This can help ensure compliance by protecting important data from accidental or malicious deletion. Locks give you a few ways to ensure your objects are retained (not deleted or overwritten). You can: * Lock objects for a specific duration, for example 90 days. * Lock objects until a certain date, for example January 1, 2030. * Lock objects indefinitely, until the lock is explicitly removed. Buckets can have up to 1,000 [bucket lock rules](https://developers.cloudflare.com/r2/buckets/). Each rule specifies which objects it covers (via prefix) and how long those objects must remain retained. Here are a couple of examples showing how you can configure bucket lock rules using [Wrangler](https://developers.cloudflare.com/workers/wrangler/): #### Ensure all objects in a bucket are retained for at least 180 days Terminal window ``` npx wrangler r2 bucket lock add --name 180-days-all --retention-days 180 ``` #### Prevent deletion or overwriting of all logs indefinitely (via prefix) Terminal window ``` npx wrangler r2 bucket lock add --name indefinite-logs --prefix logs/ --retention-indefinite ``` For more information on bucket locks and how to set retention policies for objects in your R2 buckets, refer to our [documentation](https://developers.cloudflare.com/r2/buckets/bucket-locks/).
