1 The maximum storage per account can be increased by request on Workers Paid and Enterprise plans. See the guidance on limit increases on this page to request an increase.

2 A single Worker script can have up to 1 MB of script metadata. A binding is defined as a binding to a resource, such as a D1 database, KV namespace, environmental variable or secret. Each resource binding is approximately 150-bytes, however environmental variables and secrets are controlled by the size of the value you provide. Excluding environmental variables, you can bind up to ~5,000 D1 databases to a single Worker script.
