Jukka Zitting updated OAK-2019:
-------------------------------
Attachment: 0001-OAK-2019-Compact-only-if-needed.patch
The attached patch uses a rough estimate based on referenceable bulk segments
to estimate whether running online compaction makes sense. The patch sets the
threshold at 10% of estimated space savings.
