[infinispan-dev] Cache Store Does'nt Work Async Whenever Modification is Inside Transaction

Sat Jan 30 04:58:38 EST 2010

Amin,

I did some tests too. Unfortunately, they were inconclusive...
Using JClouds BlobStore CacheStore I end up with a lot of 'other' problems
(right now, I am getting 403 from S3).
Since IMO, it is unrelated to the async behavior, I cannot help until I
solve the previous bugs.

Futures are everywhere in the code now (at least in the BlobStore) and it
makes debugging a lot harder since I cannot step easily into code.

As soon as I solve the BlobStore issues, I'll get back to this one and post
my results...
