Subject [jira] Commented: (LUCENE-2378) Cutover remaining usage of pre-flex APIs
Date Wed, 16 Jun 2010 19:02:23 GMT

Yonik Seeley commented on LUCENE-2378:
--------------------------------------

OK, I tested UnInvertedField faceting on branch_3x vs trunk:

phase1 building the UnInvertedField (involves iterating all terms and docs for a field): trunk
is 31% slower
returning top 1000 facets (exercises NumberedTermsEnum - seeking + iterating over terms):
trunk is 10% slower.

> A number of places still use the pre-flex APIs.
> This is actually healthy, since it gives us ongoing testing of the back compat emulation
layer.
> But we should at some point cut them all over to flex.  Latest we can do this is 4.0,
but I'm not sure we should do them all for 3.1... still marking this as 3.1 to "remind us"
:)
