Subject [jira] [Commented] (LUCENE-4234) Exception when FacetsCollector is used with ScoreFacetRequest
Date Sun, 22 Jul 2012 08:30:34 GMT


Gilad Barkai commented on LUCENE-4234:

Hi Shai, thank you for reviewing.

1. Merged
2. Using FBS is possible, though it's a larger change than the fix, perhaps handle this in
a seperate issue?
3. IMHO that's a waste for a large index. While allocating a large array is faster, it takes
a lot of memory - probably for no reason. Each query will take longer, but concurrent queries
will not hurt the GC that much. If the index is large concurrent queries might hit the GC
hard, perhaps even OOM ? I must admit I never measured the reallocation penalty.
