Subject RE: Client Timeouts on incrementing counters
Date Sun, 04 Dec 2011 21:37:02 GMT
I'm seeing this same problem after upgrade to 1.0.3 from .8

Nothing changed with the column family storing the counters, but now it just constantly times
out trying to increment them.  No errors in the event logs or any other issues with my cluster.

Did you find a resolution?

I have digged a bit more to try to find the root cause of the error, and I have some more
information.

It seems that all started after I upgraded Cassandra from 0.8.x to 1.0.0
When I do a incr on the CLI I also get a timeout.
row_cache_save_period_in_seconds is set to 60sec.

Could be a problem from the upgrade? I just did a rolling restart of all nodes one-by-one.

Also Cassandra logs have lots (as in, several times per second) of this message now:

INFO 14:15:25,740 Saved ClusterCassandra-CounterFamily-RowCache (52 items) in 1 ms


What does the CLI say the row_cache_save_period_in_seconds for this CF is?
