Subject [jira] Created: (LUCENE-2481) Enhance SnapshotDeletionPolicy to allow taking multiple snapshots
Date Thu, 27 May 2010 16:00:45 GMT
Enhance SnapshotDeletionPolicy to allow taking multiple snapshots

                 Key: LUCENE-2481
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Index
            Reporter: Shai Erera
            Assignee: Shai Erera
            Priority: Minor
             Fix For: 3.1, 4.0

A spin off from here:

I will:
# Replace snapshot() with snapshot(String), so that one can name/identify the snapshot
# Add some supporting methods, like release(String), getSnapshots() etc.
# Some unit tests of course.

This is mostly written already - I want to contribute it. I've also written a PersistentSDP,
which persists the snapshots on stable storage (a Lucene index in this case) to support opening
an IW with existing snapshots already, so they don't get deleted. If it's interesting, I can
contribute it as well.

Porting my patch to the new API. Should post it soon.
