All Implemented Interfaces:

java.io.Serializable, java.lang.Comparable<LeaderFollowerPartitionStateModelFactory.LeaderFollowerThreadPoolStrategy>

Enclosing class:

LeaderFollowerPartitionStateModelFactory

public static enum LeaderFollowerPartitionStateModelFactory.LeaderFollowerThreadPoolStrategy
extends java.lang.Enum<LeaderFollowerPartitionStateModelFactory.LeaderFollowerThreadPoolStrategy>

The leader follower state thread pool strategy specifies how thread pools are allocated for Helix state transition. Today, two strategies are supported: 1. single pool strategy - a single thread pool for all store version Helix state transition. 2. dual pool strategy - system has two thread pools, one for current and backup versions and a second one for future versions.
