v0.6.0

Breaking changes

• Due to some breaking changes to the metadata storage format, we recommend existing users to start with a new cluster and wipe all existing state.
• We have restricted the service key format for keyed services to only string keys. If you have any feedback about this change, let us know here #955

New features

• We now have a Java SDK to build Restate applications: https://docs.restate.dev/quickstart
• We now expose the table of the enqueued invocations in the sql introspection interface as sys_inbox
• We're publishing the container images on https://hub.docker.com/r/restatedev/restate

Notable changes

• Now the Admin API expose more metadata about service endpoints.
• Improved DELETE /invocations/:id command

We've also included some bug fixes and small improvements.

Enjoy!

Breaking changes

• Due to some breaking changes to the metadata storage format, we recommend existing users to start with a new cluster and wipe all existing state.

New features

v0.4.0

Breaking changes

• Due to some breaking changes to the storage format, we recommend existing users to start with a new cluster and wipe all existing state.
• We've updated the default ports allocation, to reduce potential conflicts with other commonly used tools. See https://docs.restate.dev/restate/deployment.
• We've simplified the definition of Protobuf service contracts for event handlers. See https://docs.restate.dev/services/sdk/kafka.
• Introduced non-backward compatible change in the built-in service dev.restate.Ingress. See https://github.com/restatedev/proto/blob/main/dev/restate/services.proto.
• This release works only with sdk-typescript >= 0.3.1

New features

• You can now provide an idempotency key when sending requests to Restate from an external client. This allows to implement end-to-end exactly once processing of requests. See https://docs.restate.dev/services/invocation#invoke-a-service-idempotently.
• The introspection SQL interface has been expanded with two new tables:
  • sys_invocation_state to inspect the status of in-flight invocations.
  • sys_journal to inspect the invocation journal.
• External ingress invocation traces now have client socket info

Among the other changes, we've also included a plethora of bug fixes and small improvements.

Enjoy!

v0.3.0

Breaking changes

Due to some breaking changes to the storage format, we recommend existing users to start with a new cluster and wipe all existing state.

Changes

• New feature: Add Kafka ingress, to read events from Kafka directly in restate services. Check the documentation https://docs.restate.dev/services/sdk/kafka for more details.
• New feature: Now you can use the function key_to_json in SQL queries to convert the service key to json
• Improvements: Now GET /service in the Admin API returns more metadata about service methods
• Various fixes

Full changelog: v0.2.1...v0.3.0

v0.2.1

What's Changed

• Rename Meta REST Operational API into Admin API by @tillrohrmann in #736
• Make Storage::Transaction a GAT by @tillrohrmann in #738

Full Changelog: v0.2.0...v0.2.1

v0.2.0

Breaking changes

Due to the amount of breaking changes, we recommend existing users to start with a new cluster and wipe all existing state. This release is compatible only with SDK versions starting from 0.2.0 (using the new versioning scheme).

Changes

• Breaking: Invocation identifiers and Awakeable identifiers now have a new string format, they are shorter and bounded (both around ~30 characters). You can safely include these identifiers in path parameters, or in headers, without any risk to hit size limits. Awakeable identifiers created with a previous release are not compatible with this release.
• New feature: Implement the dev.restate.Awakeables built-in service, to complete awakeables directly from the ingress
• New feature: Added support to reject Awakeables, that is completing an awakeable with a failure value.
• New feature: Added GET /endpoints in the admin api to retrieve the list of registered endpoints
• Breaking: Modified the DELETE /invocations in the admin api to accept the id of the invocation as path parameter: DELETE /invocations/:invocation_id
• Breaking: Modified the PartitionKey type to u64
• Various fixes

Full Changelog: v0.1.7...v0.2.0
