> 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.

> The extended statistics allows to profile Infinispan. It will be implemented a two separated modules:
> The first will give information like, for example, average transaction execution, message sizes, number of operations per transaction, etc.
> In addition, the second module will support the called top-key streaming. This technique allows to check which are the most accessed/locked/etc. keys in the application.
> I'll made the full list of the current implemented statistics soon.

---------------------------------
Summary: NullPointerException when preload with AsyncStore in Transactional caches
Key: ISPN-3216
URL: https://issues.jboss.org/browse/ISPN-3216
Project: Infinispan
Issue Type: Bug
Components: Loaders and Stores
Affects Versions: 5.3.0.CR1, 5.2.1.Final
Reporter: Pedro Ruivo
Assignee: Pedro Ruivo

AsyncStore tries to commit a transaction from preload, however this transaction has the modification list to null causing the NPE when tries to query the size.
It only happens in the transactional caches.
