(was: 5.0.0.CR3)
PUSH based rehashing
--------------------
Key: ISPN-1000
URL:
https://issues.jboss.org/browse/ISPN-1000
Project: Infinispan
Issue Type: Feature Request
Components: Distributed Cache
Affects Versions: 4.2.0.Final
Reporter: Manik Surtani
Assignee: Dan Berindei
Labels: rehash
Fix For: 5.0.0.CR4, 5.0.0.FINAL
Current rehash schemes are based on a PULL of state. Joiners (and new owners after a
leave) pull state from their neighbours. This JIRA is to reimplement this as a PUSH based
scheme, where all nodes detect new joiners (or leavers) and analyse their internal state
and determine what needs to be pushed where.
The scheme should be more robust, involving far fewer RPCs and coordination, and would
work better for merge views detected when partitions heal.
Based on Bela's prototype on
