Hi Temporal team,
Does Temporal Java SDK natively supports schedule? [Workflows | Temporal Documentation](https://docs.temporal.io/workflows#limitations) says we can use the gRPC API and method create Schedule. Can you provide more information/examples for this?

@Sowmya
you can use `createSchedule` method from the [WorkflowServiceStubs](https://www.javadoc.io/doc/io.temporal/temporal-serviceclient/latest/io/temporal/api/workflowservice/v1/WorkflowServiceGrpc.WorkflowServiceStub.html)
E.g.
```auto
WorkflowClient client = WorkflowClient.newInstance(service);
ScheduleSpec.Builder interval =
ScheduleSpec.newBuilder()
.addInterval(
IntervalSpec.newBuilder()
.setInterval(com.google.protobuf.Duration.newBuilder().setSeconds(5000).build())
.build());
NewWorkflowExecutionInfo workflowExecutionInfo =
NewWorkflowExecutionInfo.newBuilder()
.setWorkflowType(WorkflowType.newBuilder().setName("MyWorkflow").build())
.setTaskQueue(TaskQueue.newBuilder().setName("taskqueue").build())
.build();
client
.getWorkflowServiceStubs()
.blockingStub()
.createSchedule(
CreateScheduleRequest.newBuilder()
.setScheduleId("scheduleId")
.setRequestId("my-request")
.setNamespace("default")
.setSchedule(
Schedule.newBuilder()
.setSpec(interval.build())
.setAction(
ScheduleAction.newBuilder()
.setStartWorkflow(workflowExecutionInfo)
.build())
.build())
.build());
```
I will try to add this to the samples-repo [[Feature Request] sample for schedule · Issue #461 · temporalio/samples-java · GitHub](https://github.com/temporalio/samples-java/issues/461)

This is being actively worked on [here](https://github.com/temporalio/sdk-java/issues/1333) and should be done in not too long.

Thanks @antonio.perez for the quick reply. @Chad_Retz , Is there any estimate of when this will be available?

Not exactly. Hopefully soon (i.e. in `master` in days or weeks, not months).

I just now tried the above example, but facing below error:
```auto
io.grpc.StatusRuntimeException: UNIMPLEMENTED: unknown method CreateSchedule for service temporal.api.workflowservice.v1.WorkflowService
at io.grpc.stub.ClientCalls.toStatusRuntimeException(ClientCalls.java:262)
at io.grpc.stub.ClientCalls.getUnchecked(ClientCalls.java:243)

at io.temporal.api.workflowservice.v1.WorkflowServiceGrpc$WorkflowServiceBlockingStub.createSchedule(WorkflowServiceGrpc.java:3643)
```
Is there something that I’m missing here? Also, where do we specify the workflow that schedule should run? Is it the WorkflowType?

Yes, it is the workflow type,
I ran the code above with java-sdk 1.19.1. Which SDK are you using?

I had 1.15.1 earlier. Upgraded to 1.19.1 but still facing the same error.

that is weird,
can you try cloning the repo and running this example [temporal\_samples-java/HelloSchedule.java at community\_8388 · antmendoza/temporal\_samples-java · GitHub](https://github.com/antmendoza/temporal_samples-java/blob/community_8388/src/main/java/io/temporal/samples/hello/HelloSchedule.java) ?
Let me know how it goes.

Still same error:
```auto
Exception in thread "main" io.grpc.StatusRuntimeException: UNIMPLEMENTED: unknown method CreateSchedule for service temporal.api.workflowservice.v1.WorkflowService

```
May be this is related to my temporal set up for local. I’m using following docker images:
1. elasticsearch:7.16.3
2. postgres:13
3. temporalio/auto-setup:1.16.2
4. temporalio/admin-tools:1.16.2
5. temporalio/ui:0.14.1
6. temporalio/web:1.15.0

I think so @Sowmya
Schedule was added in 1.17 [https://github.com/temporalio/temporal/releases/tag/v1.17.0](https://github.com/temporalio/temporal/releases/tag/v1.17.0)
Can you pull the latest version in your local environment?

Worked with latest versions. Thanks

Hi @antonio.perez ,
We are good to use schedule feature from the below suggested solution in **production** , right? Wanted to confirm once.

Yes should be ok to use schedules for prod use cases. Would make sure service is on latest version [v1.20.3](https://github.com/temporalio/temporal/releases/tag/v1.20.3)

@antonio.perez Regarding the example that you have posted can you please let me know the following
1. What happens if two different `createSchedule` request is made with different `scheduleId` but same `requestId`? Will the second submit request throw error or it will be silently ignored?
2. `requestId` idempotency is applicable for only successful `createSchdule` request? I mean let’s say my first `createSchedule` request with `requestId1` fails for some reason then I can retry with same `requestId1` ?
3. In the documentation for Java SDK I can find mention of only [cron scheduler](https://docs.temporal.io/dev-guide/java/features#cron-schedule)? Can you please point me to the documentation where `scheduleId`, `requestId`, etc are explained?
Couple of other questions
1. From Java SDK can I get a list of all schedules?
2. Can I cancel a Schedule from Java SDK?
