Class ExecutorThreadFactory

java.lang.Object

org.apache.paimon.utils.ExecutorThreadFactory

All Implemented Interfaces:

ThreadFactory

public class ExecutorThreadFactory
extends Object
implements ThreadFactory

A thread factory intended for use by critical thread pools.

The thread factory can be given an Thread.UncaughtExceptionHandler for the threads. If no handler is explicitly given, the default handler for uncaught exceptions will log the exceptions and kill the process afterwards. That guarantees that critical exceptions are not accidentally lost and leave the system running in an inconsistent state.

Threads created by this factory are all called '(pool-name)-thread-n', where (pool-name) is configurable, and n is an incrementing number.

All threads created by this factory are daemon threads and have the default (normal) priority.
