Subject [jira] [Updated] (LUCENE-3769) Simplify NRTManager
Date Fri, 10 Feb 2012 17:28:59 GMT


Michael McCandless updated LUCENE-3769:

    Attachment: LUCENE-3769.patch

Patch; this is a great simplification of the NRTMgr API, and I think sets it up for ThingyManager.

But: I had to introduce TrackingIndexWriter, which just wraps an IndexWriter and tracks the
changes made through it (as a generation).  Previously NRTManager did this all itself, but
now you may need to share this tracking across 2 NRTManagers so I had to pull it out...

> NRTManager is hairy now, because the applyDeletes is separately passed

> I think, instead, you should pass it only to the ctor, and if you have

> I think it will also enable NRTManager to subclass ThingyManager
