New Durable Object namespaces must use the SQLite storage backend , which has been recommended for all new Durable Objects since it became generally available ↗ in 2024. Create a new class with a new_sqlite_classes migration: wrangler.jsonc wrangler.toml JSONC { " $schema " : "./node_modules/wrangler/config-schema.json" , " migrations " : [ { " tag " : "v1" , " new_sqlite_classes " : [ "MyDurableObject" ] } ] } TOML [[ migrations ]] tag = "v1" new_sqlite_classes = [ "MyDurableObject" ] SQLite-backed Durable Objects have feature parity with the key-value backend — including the key-value storage API — and additionally support relational SQL queries and point-in-time recovery to restore an object's storage to any point in the past 30 days. If you attempt to create a new key-value backed namespace (a new_classes migration) on an affected account, the deployment fails with the following error: Creating new key-value backed Durable Object namespaces is no longer supported on this account. Please create a namespace using a new_sqlite_classes migration instead. This change only affects accounts that are not already using the key-value storage backend. Accounts with at least one existing key-value backed namespace can still create new ones for now, and the Workers Free plan has only ever supported SQLite-backed Durable Objects. It is part of a broader move toward SQLite as the single storage backend for Durable Objects, ahead of a future migration path for existing key-value backed objects.
