[jira] Created: (DERBY-692) improve post commit committed delete handling when system crashes
improve post commit committed delete handling when system crashes
-----------------------------------------------------------------
Key: DERBY-692
URL: http://issues.apache.org/jira/browse/DERBY-692
Project: Derby
Type: Improvement
Components: Store
Versions: 10.0.2.0
Reporter: Mike Matrigali
Priority: Minor
Currently space reclamation of committed deleted rows is handled by queueing to an in memory list a queue of work
items when certain conditions are noticed. The usual condition is that the last row on a page has been deleted. If the
system crashes then this queue of work is lost. Work could be done during recovery to try to recover from this. Some
possibilities include:
1) modify redo of delete to queue post commit if appropriate
2) modify redo of abort of insert to queue post commit if appropriate
3) moditfy redo loop which finds page that needs no redo to check if all rows are delted and queue post commit if appropriate.
