[infinispan-issues] [JBoss JIRA] Commented: (ISPN-688) Data preloaded from a CacheStore is immediately stored in the CacheStore again

[Manik Surtani (JIRA)]

    [ https://jira.jboss.org/browse/ISPN-688?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12559368#action_12559368 ] 

Manik Surtani commented on ISPN-688:
------------------------------------

Looking at the cfg, if a chaining cache store is used, the shared/unshared flag applies to all cache stores in the chain.  :/  While that makes dealing with this bug easier, I can see this needing to change: chaining cache stores will be of limited value if they all have to be either shared or unshared.

> When enabling logging on the CacheStore, which is being used with preload=true, I can clearly see that during the preload operation each value is read from the store and immediately after that stored again.
> This is quite a performance hit in application loading, as the whole store is written again without this being needed.
