------------------------------------
Summary: Disable per-thread caching of buffers for stored fields
Key: LUCENE-9483
URL: https://issues.apache.org/jira/browse/LUCENE-9483
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Stored fields currently cache buffers that are used to decompress data. However
with one buffer per thread per segment, these buffers can start using
non-negligible amounts of data.
I think we should keep them for merges, but either remove them completely for
regular reads, or sharing them across all segments. As I'd like to avoid
relying on global threadlocals, I'm leaning towards removing them.
