Use a shared pool for background threads (rawStoreDaemon)

Key: DERBY-4210
URL: https://issues.apache.org/jira/browse/DERBY-4210
Project: Derby
Issue Type: Improvement
Components: Store
Affects Versions: 10.5.1.1
Reporter: Arnaud Masson
Use a shared pool for background threads (rawStoreDaemon).
May it could be a configuration option (pooling or not, max pool size, core
pool size, ...).
I have an application that opens several small derby databases (using
EmbeddedDriver).
Most of these instances don't handle many requests, but each instance maintains
its own thread "derby.rawStoreDaemon".
It would more efficient to use a thread pool shared by all the instances.
