Interface OperationService

All Known Subinterfaces:

InternalOperationService

All Known Implementing Classes:

OperationServiceImpl

public interface OperationService

The OperationService is responsible for executing operations.

A single operation can be executed locally using run(Operation) and execute(Operation). Or it can executed remotely using one of the send methods.

It also is possible to execute multiple operation on multiple partitions using one of the invoke methods.
