jpountz opened a new pull request, #14155: URL: https://github.com/apache/lucene/pull/14155
Currently, blocks of postings get encoded as a bit set instead of packed deltas (FOR) whenever the bit set is more storage-efficient. However, the bit set approach is quite more CPU-efficient at search time, so this PR introduces a small bias towards the bit set encoding by using it as soon as it's more storage-efficient than FOR with the next number of bits per value. The impact on storage efficiency of the Wikipedia dataset is negligible (+0.15% on `.doc` files, while `.doc` files don't dominate storage requirements, positions do) while some queries get a good speedup. -- This is an automated message from the Apache Git Service.
