LUCENE-2793: Directory#createOutput & Directory#openInput now accept an IOContext instead of a buffer size to allow low level optimizations for different usecases like merging, flushing and reading.

@ -462,6 +462,15 @@ New features
IndexSearcher. SortFields can have SortField.REWRITEABLE type which
requires they are rewritten before they are used. (Chris Male)
* LUCENE-3203: FSDirectory can now limit the max allowed write rate
(MB/sec) of all running merges, to reduce impact ongoing merging has
on searching, NRT reopen time, etc. (Mike McCandless)
* LUCENE-2793: Directory#createOutput & Directory#openInput now accept an
IOContext instead of a buffer size to allow low level optimizations for
different usecases like merging, flushing and reading.
(Simon Willnauer, Mike McCandless, Varun Thacker)
Optimizations
* LUCENE-2588: Don't store unnecessary suffixes when writing the terms
