Interface GridCacheAffinityNodeHashResolver

All Superinterfaces:

Serializable

All Known Implementing Classes:

GridCacheAffinityNodeAddressHashResolver, GridCacheAffinityNodeIdHashResolver

public interface GridCacheAffinityNodeHashResolver
extends Serializable

Resolver which is used to provide node hash value for affinity function.

Node IDs constantly change when nodes get restarted, which causes affinity mapping to change between restarts, and hence causing redundant repartitioning. Providing an alternate node hash value, which survives node restarts, will help to map keys to the same nodes whenever possible.
