Method Detail

prepare

void prepare()
      throws java.lang.Exception

In the prepare phase implementations of this interface can allocate any resources. Exception are required to be thrown directly and must not be set on the downstream.

Throws:

java.lang.Exception

start

void start()

In the start phase implementations of this interface are required to start any executors.

In this phase failures must not be propagated to downstream phases directly.

However, it is ok for the started executors to use their downstreams to propagate failures.

kill

void kill(@Nullable
          java.lang.Throwable throwable)

name

java.lang.String name()

id

int id()

cleanup

void cleanup()

Hook to cleanup the resources of this context. This might be called at any time in the lifecycle of the context.

completionFuture

java.util.concurrent.CompletableFuture<io.crate.jobs.CompletionState> completionFuture()
