@StephanEwen, @rmetzger:
I addressed the comments regarding the logs and the state id.
I also added a final improvement:
-Now compaction is executed in a background thread using a
SingleThreadedExecutor
-At empty checkpoints a keepalive call is executed against the connections
to avoid connection drops
These changes are in the last 2 commits, so if you guys +1 these last
modifications I will merge it. I guess the compaction part is the most
interesting here.
thanks
