Interface GridClientPartitionAffinity.HashIdResolver

Enclosing class:

GridClientPartitionAffinity

public static interface GridClientPartitionAffinity.HashIdResolver

This resolver is used to provide alternate hash ID, other than node ID.

Node IDs constantly change when nodes get restarted, which causes them to be placed on different locations in the hash ring, and hence causing repartitioning. Providing an alternate hash ID, which survives node restarts, puts node on the same location on the hash ring, hence minimizing required repartitioning.
