Hi Folks: I am working with on a project to save Spark dataframe to cassandra and am getting an exception regarding row size not valid (see below). I tried to trace the code in the connector and it appears that the row size (3 below) is different from the column count (which turns out be 1).  I

Hi Shalom, Thanks very much for the response! We are only using batches on one Cassandra partition to improve performance. Batches are NEVER used in this app across Cassandra partition. And if you look at the trace messages I showed, there is only one statement per batch anyway. In fact, what I

I'm using RF=2 and Write consistency = ONE, is there a counter in cassandra jmx to report number of writes that only acknowledged by one node (instead of both replica's)?  Although i don't care all replicas acknowledge the write, but i consider this as normal status of cluster. Sent using Zoho M
