Andreas, are you going to propose a patch for this or would you like
me to take the first take on it?
Hi,
I would appreciate it if you would like to take the first take on it,
since I do currently not have any code on this issue.
Thanks

change of store contract: online compress operations should not share
any locks with user transactions

Key: DERBY-1068
URL: http://issues.apache.org/jira/browse/DERBY-1068
Project: Derby
Type: Improvement
Components: Store Reporter: Andreas Korneliussen
Priority: Minor
Propose to add the following to the store contract:
* truncate and compress requires exclusive table locking
* the truncate, purge and compress operations do not share any locks
with user transactions
Currently the store implementation allows users to share locks in
truncate and possibly purge.
