> Key: LUCENE-10581

> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: Adrien Grand
> Priority: Minor
>
> This is mostly repurposing LUCENE-10573. Even though our merge policies no
> longer perform quadratic merging, it's still possible to configure them with
> low merge factors (e.g. 2) or they might decide to create unbalanced merges
> where the biggest segment of the merge accounts for a large part of the
> merge. In such cases, copying compressed data directly still yields
> significant benefits.
