Lucene 8.7 Release Highlights:

  • Better compression of stored fields. Stored fields now use dictionaries in order to improve the compression ratio when there is a lot of redundancy across documents. This works for both the BEST_SPEED and the BEST_COMPRESSION modes.
  • Faster sorting by field. When a doc-value field is also indexed with points, Lucene now takes advantage of this points index in order to skip documents whose sort value is not competitive.
  • Faster flushing of stored fields when index sorting is enabled. This can significantly speed up indexing when a non-negligible amount of data is stored in the index and index sorting is enabled.<TODO>
