applyEnvironmentVariableOverrides

public CamundaClientBuilder applyEnvironmentVariableOverrides(boolean applyEnvironmentVariableOverrides)

Description copied from interface: CamundaClientBuilder

Allows to disable the mechanism to override some properties by ENVIRONMENT VARIABLES. This is useful if a client shall be constructed for test cases or in an environment that wants to fully control properties (like Spring Boot).

The default value is true.

Specified by:

applyEnvironmentVariableOverrides in interface CamundaClientBuilder

restAddress

public CamundaClientBuilder restAddress(URI restAddress)

Specified by:

restAddress in interface CamundaClientBuilder

restAddress - the REST API address of a gateway that the client can connect to. The address must be an absolute URL, including the scheme.

The default value is https://0.0.0.0:8080.

grpcAddress

public CamundaClientBuilder grpcAddress(URI grpcAddress)

Specified by:

Parameters:

grpcAddress - the gRPC address of a gateway that the client can connect to. The address must be an absolute URL, including the scheme.

defaultTenantId

@ExperimentalApi("https://github.com/camunda/camunda/issues/14106")

public CamundaClientBuilder physicalTenantId(String physicalTenantId)

Specified by:

physicalTenantId in interface CamundaClientBuilder

Parameters:

physicalTenantId - the physical tenant identifier sent as the Camunda-Physical-Tenant gRPC metadata header on every outgoing call. When null the header is omitted and the gateway applies its own default.

public CamundaClientBuilder prefixPhysicalTenantPath(boolean prefixPhysicalTenantPath)

Description copied from interface: CamundaClientBuilder

Controls whether the client prefixes the REST base path with /physical-tenants/<id> when a physical tenant id is set (default true). Set to false to use the configured REST address verbatim — e.g. when a reverse proxy or a custom path layout already routes to the physical tenant. Has no effect on the gRPC Camunda-Physical-Tenant header, which is always sent when a physical tenant id is set.

Specified by:

prefixPhysicalTenantPath in interface CamundaClientBuilder

Parameters:

prefixPhysicalTenantPath - whether to auto-prefix the REST base path per physical tenant

defaultJobWorkerTenantIds

@ExperimentalApi("https://github.com/camunda/camunda/issues/14106")

Specified by:

numJobWorkerExecutionThreads in interface CamundaClientBuilder

Parameters:

jobWorkerExecutor

public CamundaClientBuilder jobWorkerExecutor(ScheduledExecutorService executor,
 boolean takeOwnership)

Description copied from interface: CamundaClientBuilder

Identical behavior as CamundaClientBuilder.jobWorkerSchedulingExecutor(ScheduledExecutorService,boolean). Replaced in favor of more fine-grained configuration of job worker executors.

Specified by:

jobWorkerSchedulingExecutor

public CamundaClientBuilder jobWorkerSchedulingExecutor(ScheduledExecutorService executor,
 boolean takeOwnership)

Description copied from interface: CamundaClientBuilder

Allows passing a custom scheduled executor service that will be used for scheduling job worker tasks such as polling for new jobs.

Note that job handling (i.e. executing the JobHandler) is done on a separate executor configured via CamundaClientBuilder.jobHandlingExecutor(ExecutorService, boolean).

If no job handling executor is provided, this scheduling executor will also be used for job handling. If no executor is provided here, a default scheduled executor will be created.

Specified by:

jobWorkerSchedulingExecutor in interface CamundaClientBuilder

Parameters:

executor - an executor service to use for scheduling job worker tasks

takeOwnership - if true, the executor will be closed when the client is closed otherwise, it's up to the caller to manage its lifecycle

See Also:

• CamundaClientBuilder.jobHandlingExecutor(ExecutorService, boolean)

jobHandlingExecutor

public CamundaClientBuilder jobHandlingExecutor(ExecutorService executor,
 boolean takeOwnership)

Description copied from interface: CamundaClientBuilder

Allows passing a custom executor service that will be used for handling jobs (i.e. executing the JobHandler). This executor is separate from the scheduling executor configured via CamundaClientBuilder.jobWorkerSchedulingExecutor(ScheduledExecutorService, boolean).

If no executor is provided here, the scheduling executor will also be used for job handling.

When non-null, this setting override CamundaClientBuilder.numJobWorkerExecutionThreads(int).

Specified by:

jobHandlingExecutor in interface CamundaClientBuilder

Parameters:

executor - an executor service to use for handling jobs

takeOwnership - if true, the executor will be closed when the client is closed otherwise, it's up to the caller to manage its lifecycle
