Tomasz Grabiec commented on CASSANDRA-5483:
-------------------------------------------
This change seems to have changed the behavior of "nodetool flush" to not flush
the system keyspace (see CASSANDRA-11830).

I wonder what is the rationale for this.

> I think it would be nice to log repair stats and results like query tracing
> stores traces to system keyspace. With it, you don't have to lookup each log
> file to see what was the status and how it performed the repair you invoked.
> Instead, you can query the repair log with session ID to see the state and
> stats of all nodes involved in that repair session.
