jpountz opened a new pull request, #13267:
URL: https://github.com/apache/lucene/pull/13267
This switches the following files to `IOContext#RANDOM`:
- Stored fields data file.
- Term vectors data file.
- HNSW graph.
- Temporary file storing vectors at merge time that we use to construct the
merged HNSW graph.
- Vector data files, including quantized data files.
I hesitated using `IOContext.RANDOM` on terms, since they have a random
access pattern when running term queries, but a more sequential access pattern
when running multi-term queries. I erred on the conservative side and did not
switch them to `IOContext.RANDOM` for now.
For simplicity, I'm only touching the current codec, not previous codecs.
