Date Thu, 01 Nov 2012 21:36:12 GMT


Simon Willnauer updated LUCENE-4515:

    Attachment: LUCENE-4515.patch

alright guys. Here is a new patch that accepts a long instead of the allocators indicating
an upper memory bound for reusing buffers in the pools if reset is called. I think this should
make everybody happy and we can move forward here! lemme know what you think!

> Currently MemoryIndex uses BytesRef objects to represent terms and holds an int[] per
term per field to represent postings. For highlighting this creates a ton of objects for each
search that 1. need to be GCed and 2. can't be reused.
