[PR] Use FixedLengthBytesRefArray in OneDimensionBKDWriter to hold split values [lucene]
iverase opened a new pull request, #14383:
URL: https://github.com/apache/lucene/pull/14383
We are currently using a list which feels wasteful. For example looking into the heap dump on an IP field, we were using almost double of the heap necessary to hold the split values:

Using FixedLengthBytesRefArray should reduce memory usage and avoid humongous allocations.
