Thanks Maki and Tyler.
Re: Q1: I think its the time for me to think about LevelCompaction at this
time. But I'm happy to know I can run major compactions as often as I like
if I can afford.
Re: Q2: Other than the high IO impact if there won't be any data
corruption/consistency issues I think I ca
At this point, using LeveledCompaction is a much better way to have good
guarantees about how many sstables your reads will hit (and thus better
latency guarantees) than SizeTiered with periodic major compactions.

DataStax has not recommend to run major compaction now:

But if you can afford it, major compaction will improve read latency as you see.
Major compaction is expensive, so you will not want to run it during
high traffic hours. And you should not
Hi,
I have two questions on major compactions (the ones user initiate using
nodetool) and I really appreciate if someone can help.
1. I've noticed that when I run compactions the read latency improves even
more than I expected (which is good :) ) The improvement is so tempting
that I'd like to ru
