Class ThreadPool

java.lang.Object

org.bytedeco.javacpp.Pointer

org.bytedeco.arrow.Executor

org.bytedeco.arrow.ThreadPool

All Implemented Interfaces:

AutoCloseable

@Namespace(value="arrow::internal")
 @NoOffset
 @Properties(inherit=arrow.class)
public class ThreadPool
extends Executor

An Executor implementation spawning tasks in FIFO manner on a fixed-size pool of worker threads. Note: Any sort of nested parallelism will deadlock this executor. Blocking waits are fine but if one task needs to wait for another task it must be expressed as an asynchronous continuation.
