LUCENE-10661: Move CHANGES entry to 9.4.
> Reduce memory copy in BytesStore
> --------------------------------
>
> Key: LUCENE-10661
> URL: https://issues.apache.org/jira/browse/LUCENE-10661
> Project: Lucene - Core
> Issue Type: Improvement
> Reporter: LuYunCheng
> Priority: Major
> Fix For: 9.4
>
> Time Spent: 1h
> Remaining Estimate: 0h
>
> This is derived from
> [LUCENE-10627](https://github.com/apache/lucene/pull/987) AND
> [LUCENE-10657](https://github.com/apache/lucene/pull/1034)
> The abstract method copyBytes in DataOutput have to copy from input to a
> copyBuffer and then write into BytesStore.blocks, which is called in FST
> initialization read from metaIn.
> Although, this copy bytes only a few bytes (in the testscase only 3-10
> bytes), i think we can save this memory copy, just save the
> DataOutput.copyBytes to create new copyBuffer with 16384 bytes
