⚠️ Note: There is a regression in this release with worker_task_slots_available for local activities where it may not be emitted properly and the slot may not be properly released in all situations. We recommend users use v1.24.1.

Highlights

Slot Auto-Tuning (Preview)

Added WorkerTuner - this wraps the previously added SlotSupplier classes to bring worker tuning options together under one class passed to the WorkerOptions
* Added ResourceBasedTuner and ResourceBasedSlotSupplier - these classes can be used to tune the workers slot count based on available memory and cpu resources.
Set a memory/cpu target and the worker will automatically try to reach those target usage levels.
* Added CompositeTuner - this allows you to combine different kinds of SlotSuppliers to implement WorkerTuner.

Please give the resource based tuning a try and let us know how it works for you (feedback on community slack is welcome)!
The easiest thing to do is instantiate and pass a ResourceBasedTuner to WorkerOptions.
It'll work best if the worker is the only thing on your host using significant resources.
Try setting the thresholds to a reasonable value like 0.8, and make sure that your JVM -Xmx value is set appropriately.

Note: Custom Slot Supplier is currently considered experimental and not intended for production use.

Breaking Changes

Workflow Update (Preview)

This release includes some breaking changes to the Workflow Update client API.

  • temporal.client.UpdateOptions.setWaitPolicy has been changed to temporal.client.UpdateOptions.setWaitForStage
  • WaitForStage is now a required option in temporal.client.UpdateOptions and no longer defaults to Accepted
  • io.temporal.client.WorkflowStub.startUpdate now requires a WorkflowUpdateStage.
  • io.temporal.client.WorkflowStub.startUpdate now respects the WorkflowUpdateStage.
    • Previously startUpdate may have returned a handle before the desired WaitForStage was reached.

SpringBoot Integration (Preview)

As part of preparation for Spring Boot Integration GA we have renamed our Spring Boot packages to remove the alpha tag:
* temporal-spring-boot-starter-alpha -> temporal-spring-boot-starter
* temporal-spring-boot-autoconfigure-alpha -> temporal-spring-boot-autoconfigure

Users should update their package names when upgrading the Java SDK.

Stay tuned for future news about SpringBoot integration GA.
