JDBCDescriptorStore

[Chad Brandt <cb...@mn.rr.com>]

Does anyone know if the JDBCDescriptorStore use any kind of connection 
pooling? I am wondering how performance will be if not.

Chad,

I suppose you meant JDBCDescriptorsStore.  No it doesn't use connection pool
so you'll have to add your own.  But the biggest bottleneck comes from two
places:

1. It extends AbstractSimpleService which supports only a single transaction
context.
2. All database operations share a single and global jdbc connection.

So above means if you have concurrent transactions, one thread will block
and rollback after times out.  This has been resolved by the new
J2EEDescriptorsStore.
