This has a lot of improvements in lucene, particularly around memory usage, merging, safety, compressed bitsets, etc. On the elasticsearch side, summary of the larger changes: API changes: postings API became a "pull" rather than "push", collector API became per-segment, etc. packaging changes: add lucene-backwards-codecs.jar as a dependency. improvements to boolean filtering: especially ensuring it will not be slow for SparseBitSet. use generic BitSet api in plumbing so that concrete bitset type is an implementation detail. use generic BitDocIdSetFilter api for dedicated bitset cache, so there is type safety. changes to support atomic commits implement Accountable.getChildResources (detailed memory usage API) for fielddata, etc change handling of IndexFormatTooOld/New, since they no longer extends CorruptIndexException Closes #8347.
