      Description

      Per-row bloom filters may be a misfeature.

      On small rows we don't create them.

      On large rows we essentially only do slice queries that can't take advantage of it.

      And on very large rows if we ever did deserialize it, the performance hit of doing so would outweigh the benefit of skipping the actual read.
