----------------------------------
Resolution: Fixed
> 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
> Priority: Minor
> Fix For: 8.7

> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
