[infinispan-issues] [JBoss JIRA] (ISPN-2862) Integrate the Self-tuning Data Placement from CloudTM into Infinispan

[Pedro Ruivo (JIRA)]

     [ https://issues.jboss.org/browse/ISPN-2862?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Pedro Ruivo updated ISPN-2862:
------------------------------

    Description: 
With the same goal as L1 Cache, it applies a different technique to reduce the communication overhead. The self-tunning data placement detects which are the keys most accessed by each node, modifies the ConsistentHash and triggers the State Transfer in order to move the keys for that nodes.

The main difference for L1 Cache is the fact that L1 creates a new copy of the <key,value> in the requestor node, that needs to be invalidated later. The Data Placement, really moves the <key,value> to that requestor. 

Both techniques can be enabled at the same time.

This module depends of ISPN-2861, namely the top-key module.

  was:This is a smarter L1 implementation.
