    Description

      Using a sparse bitset in SingleValueDocValuesFieldUdpates allows storing
      which documents have an update much more efficient and prevents the need
      to sort the docs array altogether that showed to be a significant bottleneck
      in LUCENE-8598. Using the spares bitset yields another 10x performance improvement
      in applying updates versus the changes proposed in LUCENE-8598.
