enhance derby inplace compress defragment phase to hold locks for less time.
----------------------------------------------------------------------------
Key: DERBY-1188
URL: http://issues.apache.org/jira/browse/DERBY-1188
Project: Derby
Type: Improvement
Components: Store
Versions: 10.1.1.0, 10.1.1.1, 10.1.1.2, 10.1.2.0, 10.1.2.1, 10.1.2.2,
10.1.2.3, 10.2.0.0
Reporter: Mike Matrigali
Priority: Minor
Currently the truncate defragment pass holds locks until it commits. It would
be better if it committed more often. To do this
the loop must be enhanced to pick up ddl level state change when the commits
happen and release locks. It may be that
work being done in 10.2 for scrollable updatable result sets across commits in
open cursors will help with this.
