    - `state?: "enabled" | "disabled"`

      Updates the state optionally.

      - `"enabled"`

      - `"disabled"`

    - `target_size_mb?: "64" | "128" | "256" | "512"`

      Updates the target file size optionally.

      - `"64"`

      - `"128"`

      - `"256"`

      - `"512"`

  - `snapshot_expiration?: SnapshotExpiration`

    Body param: Updates snapshot expiration configuration (all fields optional).

    - `max_snapshot_age?: string`

  Configures maintenance for the catalog.

  - `compaction?: Compaction`

    Configures compaction for catalog maintenance.

    - `state: "enabled" | "disabled"`

      Specifies the state of maintenance operations.

      - `"enabled"`

      - `"disabled"`

    - `target_size_mb: "64" | "128" | "256" | "512"`

      Sets the target file size for compaction in megabytes. Defaults to "128".

      - `"64"`

      - `"128"`

      - `"256"`

      - `"512"`

  - `snapshot_expiration?: SnapshotExpiration`

    Configures snapshot expiration settings.

    - `max_snapshot_age: string`

      Specifies the maximum age for snapshots. The system deletes snapshots older than this age.
      Format: <number><unit> where unit is d (days), h (hours), m (minutes), or s (seconds).

      Defaults to "7d".

    - `min_snapshots_to_keep: number`

      Specifies the minimum number of snapshots to retain. Defaults to 100.

    - `state: "enabled" | "disabled"`

      Specifies the state of maintenance operations.

```node
import Cloudflare from 'cloudflare';

const client = new Cloudflare({
  apiToken: process.env['CLOUDFLARE_API_TOKEN'], // This is the default and can be omitted
});

const maintenanceConfig = await client.r2DataCatalog.maintenanceConfigs.update('my-data-bucket', {
  account_id: '0123456789abcdef0123456789abcdef',
  compaction: { state: 'enabled', target_size_mb: '256' },
  snapshot_expiration: {
