Interface WorkerKind

All Known Implementing Classes:
DndWorkerKind, EnterpriseWorkerKind, GenericCommandWorkerKind
public interface WorkerKind
The WorkerKind class is used to map instructions from the RemoteProcessingRequest into the appropriate worker control invocations to create the requested worker. The default worker kind is a Deephaven Enterprise worker, the same version as the dispatcher. The alternative worker kind that we are most interested in is a Deephaven community worker.
