Method Detail

getExperiments

@Experimental
 @Nullable
java.util.List<java.lang.String> getExperiments()

The list of backend experiments to enable.

Dataflow provides a number of experimental features that can be enabled with this flag.

Please sync with the Dataflow team before enabling any experiments.

setExperiments

void setExperiments(@Nullable
                    java.util.List<java.lang.String> value)

getApiRootUrl

@Default.String(value="https://dataflow.googleapis.com/")
java.lang.String getApiRootUrl()

The root URL for the Dataflow API. dataflowEndpoint can override this value if it contains an absolute URL, otherwise apiRootUrl will be combined with dataflowEndpoint to generate the full URL to communicate with the Dataflow API.

setApiRootUrl

void setApiRootUrl(java.lang.String value)

getDataflowEndpoint

@Default.String(value="")
java.lang.String getDataflowEndpoint()

Dataflow endpoint to use.

Defaults to the current version of the Google Cloud Dataflow API, at the time the current SDK version was released.

If the string contains "://", then this is treated as a URL, otherwise getApiRootUrl() is used as the root URL.

setDataflowEndpoint

void setDataflowEndpoint(java.lang.String value)

getDataflowJobFile

java.lang.String getDataflowJobFile()

The path to write the translated Dataflow job specification out to at job submission time. The Dataflow job specification will be represented in JSON format.

setDataflowJobFile

void setDataflowJobFile(java.lang.String value)

getStagerClass

@Default.Class(value=GcsStager.class)
java.lang.Class<? extends Stager> getStagerClass()

The class responsible for staging resources to be accessible by workers during job execution. If stager has not been set explicitly, an instance of this class will be created and used as the resource stager.

setStagerClass

void setStagerClass(java.lang.Class<? extends Stager> stagerClass)

getStager

@Default.InstanceFactory(value=DataflowPipelineDebugOptions.StagerFactory.class)
Stager getStager()

The resource stager instance that should be used to stage resources. If no stager has been set explicitly, the default is to use the instance factory that constructs a resource stager based upon the currently set stagerClass.

setStager

void setStager(Stager stager)

getDataflowClient

@Default.InstanceFactory(value=DataflowPipelineDebugOptions.DataflowClientFactory.class)
com.google.api.services.dataflow.Dataflow getDataflowClient()

An instance of the Dataflow client. Defaults to creating a Dataflow client using the current set of options.

setDataflowClient

void setDataflowClient(com.google.api.services.dataflow.Dataflow value)

getTransformNameMapping

java.util.Map<java.lang.String,java.lang.String> getTransformNameMapping()

Mapping of old PTranform names to new ones, specified as JSON {"oldName":"newName",...}. To mark a transform as deleted, make newName the empty string.

setTransformNameMapping

void setTransformNameMapping(java.util.Map<java.lang.String,java.lang.String> value)

getOverrideWindmillBinary

java.lang.String getOverrideWindmillBinary()

Custom windmill_main binary to use with the streaming runner.

setOverrideWindmillBinary

void setOverrideWindmillBinary(java.lang.String value)

getWindmillServiceEndpoint

java.lang.String getWindmillServiceEndpoint()

Custom windmill service endpoint.

setWindmillServiceEndpoint

void setWindmillServiceEndpoint(java.lang.String value)

getWindmillServicePort

@Default.Integer(value=443)
int getWindmillServicePort()

setWindmillServicePort

void setWindmillServicePort(int value)

getNumberOfWorkerHarnessThreads

int getNumberOfWorkerHarnessThreads()

Number of threads to use on the Dataflow worker harness. If left unspecified, the Dataflow service will compute an appropriate number of threads to use.

setNumberOfWorkerHarnessThreads

void setNumberOfWorkerHarnessThreads(int value)

getDumpHeapOnOOM

boolean getDumpHeapOnOOM()

If true, save a heap dump before killing a thread or process which is GC thrashing or out of memory. The location of the heap file will either be echoed back to the user, or the user will be given the opportunity to download the heap file.

CAUTION: Heap dumps can of comparable size to the default boot disk. Consider increasing the boot disk size before setting this flag to true.

setDumpHeapOnOOM

void setDumpHeapOnOOM(boolean dumpHeapBeforeExit)
