Turn off compaction during business hours

runCompactor Compaction is consuming 100% CPU for 10 mins everyday at sporadic time with 100s of Go routines. I’d like to turn compaction off during businesss hours. Is there a way to customize compaction time to set it not to run during business hours between 8am and 5am?

You could set opts.NumCompactors to zero which I think will disable auto compaction and then manually compact at times more convenient for you.

How do I run manual compaction in Go?
