StreamJobsCommandImpl

public StreamJobsCommandImpl(GatewayGrpc.GatewayStub asyncStub,
 JsonMapper jsonMapper,
 Predicate<Throwable> retryPredicate,
 ZeebeClientConfiguration config)

Method Details

requestTimeout

public FinalCommandStep<StreamJobsResponse> requestTimeout(Duration requestTimeout)

Description copied from interface: FinalCommandStep

Sets the request timeout for the command. The default request timeout can be configured using ZeebeClientBuilder.defaultRequestTimeout(Duration).

Specified by:

requestTimeout in interface FinalCommandStep<StreamJobsResponse>

Parameters:

requestTimeout - the request timeout

Returns:

the configured command

send

public ZeebeFuture<StreamJobsResponse> send()

Description copied from interface: FinalCommandStep

Sends the command to the Zeebe broker. This operation is asynchronous. In case of success, the future returns the event that was generated by the Zeebe broker in response to the command.

Call ZeebeFuture.join() to wait until the response is available.

 Future<JobEvent&#62 future = command.send();
 JobEvent event = future.join();
 

Specified by:

send in interface FinalCommandStep<StreamJobsResponse>

Returns:

a future tracking state of success/failure of the command.

jobType

public StreamJobsCommandStep1.StreamJobsCommandStep2 jobType(String jobType)

Description copied from interface: StreamJobsCommandStep1

Set the type of jobs to work on; only jobs of this type will be activated and consumed by this stream.

Specified by:

jobType in interface StreamJobsCommandStep1

Parameters:

jobType - the type of jobs (e.g. "payment")

Returns:

the builder for this command

consumer

public StreamJobsCommandStep1.StreamJobsCommandStep3 consumer(Consumer<ActivatedJob> consumer)

Description copied from interface: StreamJobsCommandStep1.StreamJobsCommandStep2

Sets the consumer to receive activated jobs. Note that jobs can be activated on different threads, so the consumer should be thread-safe.

Specified by:

consumer in interface StreamJobsCommandStep1.StreamJobsCommandStep2

Parameters:

consumer - the job consumer

Returns:

the builder's next step

timeout

public StreamJobsCommandStep1.StreamJobsCommandStep3 timeout(Duration timeout)

Description copied from interface: StreamJobsCommandStep1.StreamJobsCommandStep3

Set the time for how long a job is exclusively assigned for this subscription.

In this time, the job can not be assigned by other subscriptions to ensure that only one subscription work on the job. When the time is over then the job can be assigned again by this or other subscription if it's not completed yet.

If no time is set then the default is used from the configuration.

Specified by:

timeout in interface StreamJobsCommandStep1.StreamJobsCommandStep3

Parameters:

timeout - the time as duration (e.g. "Duration.ofMinutes(5)")

Returns:

the builder for this command. Call FinalCommandStep.send() to complete the command and send it to the broker.

workerName

public StreamJobsCommandStep1.StreamJobsCommandStep3 workerName(String workerName)

Description copied from interface: StreamJobsCommandStep1.StreamJobsCommandStep3

Set the name of the job worker.

This name is used to identify the worker which activated the jobs. Its main purpose is for monitoring and auditing. Commands on activated jobs do not check the worker name, i.e. complete or fail job.

If no name is set then the default is used from the configuration.

Specified by:

workerName in interface StreamJobsCommandStep1.StreamJobsCommandStep3

Parameters:

workerName - the name of the worker (e.g. "payment-service")

Returns:

the builder for this command. Call FinalCommandStep.send() to complete the command and send it to the broker.

fetchVariables

public StreamJobsCommandStep1.StreamJobsCommandStep3 fetchVariables(List<String> fetchVariables)

Description copied from interface: StreamJobsCommandStep1.StreamJobsCommandStep3

Set a list of variable names which should be fetch on job activation.

The jobs which are activated by this command will only contain variables from this list.

This can be used to limit the number of variables of the activated jobs.

Specified by:

fetchVariables in interface StreamJobsCommandStep1.StreamJobsCommandStep3

Parameters:

fetchVariables - list of variables names to fetch on activation

Returns:

the builder for this command. Call FinalCommandStep.send() to complete the command and send it to the broker.

fetchVariables

public StreamJobsCommandStep1.StreamJobsCommandStep3 fetchVariables(String... fetchVariables)

Description copied from interface: StreamJobsCommandStep1.StreamJobsCommandStep3

Set a list of variable names which should be fetched on job activation.

The jobs which are activated by this command will only contain variables from this list.

This can be used to limit the number of variables of the activated jobs.

Specified by:

fetchVariables in interface StreamJobsCommandStep1.StreamJobsCommandStep3

Parameters:

fetchVariables - list of variables names to fetch on activation

Returns:

the builder for this command. Call FinalCommandStep.send() to complete the command and send it to the broker.

tenantId

public StreamJobsCommandStep1.StreamJobsCommandStep3 tenantId(String tenantId)

Description copied from interface: CommandWithOneOrMoreTenantsStep

Experimental: This method is under development, and as such using it may have no effect on the command builder when called. While unimplemented, it simply returns the command builder instance unchanged. This method already exists for software that is building support for multi-tenancy, and already wants to use this API during its development. As support for multi-tenancy is added to Zeebe, each of the commands that implement this method may start to take effect. Until this warning is removed, anything described below may not yet have taken effect, and the interface and its description are subject to change.

Specifies the tenant that will own any entities (e.g. process definition, process instances, etc.) resulting from this command, or that owns any entities (e.g. jobs) referred to from this command.

Multi-tenancy

Multiple tenants can share a Zeebe cluster. Entities can be assigned to a specific tenant using an identifier. Only that tenant can access these entities.

Any entities created before multi-tenancy has been enabled in the Zeebe cluster, are assigned to the CommandWithTenantStep.DEFAULT_TENANT_IDENTIFIER.

If no tenant is explicitly specified, then the command is rejected.

One or more tenants

This method can be called multiple times to specify multiple tenants.

This can be useful when requesting jobs for multiple tenants at once. Each of the activated jobs will be owned by the tenant that owns the corresponding process instance.

Specified by:

tenantId in interface CommandWithOneOrMoreTenantsStep<StreamJobsCommandStep1.StreamJobsCommandStep3>

Specified by:

tenantId in interface CommandWithTenantStep<StreamJobsCommandStep1.StreamJobsCommandStep3>

Parameters:

tenantId - the identifier of the tenant to specify for this command, e.g. "ACME"

Returns:

the builder for this command with the tenant specified

tenantIds

public StreamJobsCommandStep1.StreamJobsCommandStep3 tenantIds(List<String> tenantIds)

Description copied from interface: CommandWithOneOrMoreTenantsStep

Specifies the tenants that may own any entities (e.g. process definition, process instances, etc.) resulting from this command.

One or more tenants

This can be useful when requesting jobs for multiple tenants at once. Each of the activated jobs will be owned by the tenant that owns the corresponding process instance.

Specified by:

tenantIds in interface CommandWithOneOrMoreTenantsStep<StreamJobsCommandStep1.StreamJobsCommandStep3>

Parameters:

tenantIds - the identifiers of the tenants to specify for this command, e.g. ["ACME", "OTHER"]

Returns:

the builder for this command with the tenants specified

See Also:

• CommandWithOneOrMoreTenantsStep.tenantId(String)

tenantIds

public StreamJobsCommandStep1.StreamJobsCommandStep3 tenantIds(String... tenantIds)

Description copied from interface: CommandWithOneOrMoreTenantsStep

Shorthand method for CommandWithOneOrMoreTenantsStep.tenantIds(List).

Specified by:

tenantIds in interface CommandWithOneOrMoreTenantsStep<StreamJobsCommandStep1.StreamJobsCommandStep3>

Parameters:

tenantIds - the identifiers of the tenants to specify for this command, e.g. ["ACME", "OTHER"]

Returns:

the builder for this command with the tenants specified
