(was: Hi,
sorry for bothering, but do I need extra permissions to assign the issue to me [I have no access to assign button for now]?
I've already submitted a kind of patch, but still have several questions because I'm new here and may miss the spirit of C* development:
1. Do C* really need such functionality? [the question exists because provided solution changes the schema of system.compaction_history table and there are several cases, when it is not appropriate to do such things]
2. I assume, that "compaction_started_at" may be not a really good name, so should I think about more conscious one? Or, maybe someone has the proper name for that column on the fly.
3. Current solution shows "unix start time" instead of compaction start time if it is not present [via nodetool compactionhistory] - are you ok with such approach? Or is it better to output a kind of special symbol, for example - "-"?
4. As far as I investigated, C* performs "force" update for system tables and I should not think about any special upgrade utility for now providing such patch, am I right?
Thank you!)

> Compaction history does not currently contain the completion time stamp which can be beneficial in determining performance and event tracing. I would like to use this information also in our Health Check process to trace event timelines.
