How to pick which region(s) to major compact?
Otis Gospodnetic 2012-12-12, 20:19
Hi,

If you want to do major compaction on a single region at a time (to
minimize the impact on the cluster), how do you pick which region to
compact?

What should one look for in order to get the best ROI out of major
compaction - the best ratio of the negative impact and positive benefit
- and is there a programmatic way to get to this information, so region
selection+compaction can be automated?

Thanks,
Otis
