jpountz opened a new pull request, #11917:
URL: https://github.com/apache/lucene/pull/11917
The default codec has a number of small and hot files, that actually used to
be fully loaded in memory before we moved them off-heap. In the general case,
these files are expected to fully fit into the page cache for things to work
well. Should we give control over preloading to codecs? This is what this
commit does for the following files:
- Terms index (`tip`)
- Points index (`kdi`)
- Stored fields index (`fdx`)
- Terms vector index (`tvx`)
This only has an effect on `MMapDirectory`.
