Subject Re: Caching and transactions

There is a small potential for that. IBatis allows for you to configure
your cache to flush when a statement is called. So, in a case where
someone was performing an update that flushed a cache and then called a
select that repopulated that same cache in the same transaction which
subsequently failed, then that there would be invalid cached objects. I
suppose we could fix that by retaining a session scoped cache for that
particular transaction/thread and committing it to the global cache upon
completion of the transaction.

I was wondering if caches get cleared once a transaction has failed or
has been rolled back? If not, couldn't they contain invalid entries?
As caches seem to be global, what about isolation of different
concurrent transactions from each other?
