successful, the new data has been written to a log file - so that if there
is a crash your data is safe. Is this correct?
If the above is correct, there is something going on that I don't
understand. Are the log files to
By default Cassandra syncs the commit log to disk periodically, so if you
are looking at file sizes, you won't see the most up to date numbers. This
is just like how if you tail a file that isn't flushing frequently, you
might wait a little while before you see the updates.
In periodic mode,
Thank you very much! I now understand things much better.
However, my configuration is as follows:
CommitLogSyncperiodic/CommitLogSync
CommitLogSyncPeriodInMS1/CommitLogSyncPeriodInMS
So I should see my commit log change after 10,000 milliseconds = 10 seconds?
It seems to take much
Is your IO under heavy load? If it is, that may be the cause, otherwise I'm

Can you please tell whether there is a cassandra tool modeling data, which
provides a standard way to define the data and relations between them,
similar Entity-relation diagram in relational databases?
