public sealed class WorkerPool : IMessage<WorkerPool>, IEquatable<WorkerPool>, IDeepCloneable<WorkerPool>, IBufferMessage, IMessageReference documentation and code samples for the Dataflow v1beta3 API class WorkerPool.
Describes one particular pool of Cloud Dataflow workers to be instantiated by the Cloud Dataflow service in order to perform the computations required by a job. Note that a workflow job may use multiple pools, in order to match the various computational requirements of the various stages of the job.

NumThreadsPerWorker
public int NumThreadsPerWorker { get; set; }The number of threads per worker harness. If empty or unspecified, the service will choose a number of threads (according to the number of cores on the selected machine type for batch, or 1 by convention for streaming).
| Property Value | |
|---|---|
| Type | Description |
int | |
NumWorkers
public int NumWorkers { get; set; }Number of Google Compute Engine workers in this pool needed to execute the job. If zero or unspecified, the service will attempt to choose a reasonable default.

TeardownPolicy
public TeardownPolicy TeardownPolicy { get; set; }Sets the policy for determining when to turndown worker pool.
Allowed values are: TEARDOWN_ALWAYS, TEARDOWN_ON_SUCCESS, and
TEARDOWN_NEVER.
TEARDOWN_ALWAYS means workers are always torn down regardless of whether
the job succeeds. TEARDOWN_ON_SUCCESS means workers are torn down
if the job succeeds. TEARDOWN_NEVER means the workers are never torn
down.
If the workers are not torn down by the service, they will
continue to run and use Google Compute Engine VM resources in the
user's project until they are explicitly terminated by the user.
Because of this, Google recommends using the TEARDOWN_ALWAYS
policy except for small, manually supervised test jobs.
If unknown or unspecified, the service will attempt to choose a reasonable default.
| Property Value | |
|---|---|
| Type | Description |
TeardownPolicy | |
WorkerHarnessContainerImage
public string WorkerHarnessContainerImage { get; set; }Required. Docker container image that executes the Cloud Dataflow worker harness, residing in Google Container Registry.
