Re: cassandro nodes restarts


It’s a warning, but probably not causing you problems

A 20kB batch is a hint that your batches are larger than Cassandra expects, but the 5k limit for that logger was somewhat arbitrary, and I would be shocked if 20kB batches were a problem unless you were already close to tipping your cluster

If I were you I’d disable that warning (or set it much higher).
