Summary: Preload with async cache store is not efficient

Fixed In Version: Doc Type: Bug Fix
Doc Text:
Configuring an asynchronous cache store with 'preload' enabled leads to pre-loading each entry in the store in a loop, each entry being loaded through a store read. This has been fixed. Pre-loading entries from a cache store is now more efficient and does not require loading each entry through a store read.

Description Mircea Markus 2014-01-29 23:38:42 UTC 
Description of problem:
Configuring on a AdvancedCacheLoader preload=true and asyn=true cause it to load each entry in the store in a loop, each entry being loaded through an store read.
This is caused by the way loadAll is implemented in the AsynLoader: in order to enforce consistency with whatever is in memory it does some special handling. The thing is, though, that we don't need this advanced async loader logic during the initial preload, as the async cache loader is empty.
