[jboss-jira] [JBoss JIRA] Updated: (JBCACHE-1221) JDBCCacheLoader optimizations

[Mircea Markus (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBCACHE-1221?page=all ]

Mircea Markus updated JBCACHE-1221:
-----------------------------------


When changing an attribute in a node, the entire Map blob is rewritten to disk. This is a major performance drawback, check whether we can persist each changed attribute individually. 
For performance figures, see http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129788#4129788

> JDBCCacheLoader optimizations:
> - batch cache put operations during state transfer
> - batch put operations on transactions as follows:
>                     - batch all the puts and flush on transaction commit
>                     - if an remove takes place at some point, then flush before the remove (guess I'll also have to flush before a get takes place in the same transaction, have to check that)
