Nate,

 

What values for the FlushWriter line would draw concern to you?  What is the difference between Blocked and All Time Blocked?

What was the impetus for turning up the commitlog_segment_size_in_mb? 

 

Also, in nodetool tpstats, do what are the values for the FlushWriter line?

We’re running 2.0.5, recently upgraded from 1.2.14.

 

Sometimes we are seeing CommitLogs starting to build up.

 

Is this a potential bug? Or a symptom of something else we can easily address?

 

We have

commitlog_sync: periodic

commitlog_sync_period_in_ms:10000

commitlog_segment_size_in_mb: 512

 

 

Thanks,

Chris
