…default High compaction score keeps more rowset metadata, delete bitmaps, and version graph state in memory. Pausing compaction on high memory makes those high-score tablets harder to merge, so metadata backlog and memory pressure become harder to bring down. Disable this pause by default to avoid reinforcing that feedback loop.

High compaction score keeps more rowset metadata,
delete bitmaps, and version graph state in
memory.
Pausing compaction on high memory makes those
high-score tablets harder to merge, so
metadata backlog and memory pressure become
harder to bring down.
Disable this pause by default to avoid
reinforcing that feedback loop.
