Cassandra proxy to control read/write throughput

Hi, I am using different versions of Casandra in my environment where I have 60 nodes are running for different applications. Each application is connecting to its own cluster. I am thinking about abstracting the Cassandra IP from app drivers. App will communicate to one proxy IP which will

Re: code snippet for cqlsh COPY from

Hi Suresh, cqlsh COPY does batches intelligently by only grouping inserts targeting the same partition in a batch. As of version 3.6, C* will not emit the "batch size exceeded" errors if all statements in a batch belong to the same partition (CASSANDRA-13467

Re: server connection in authenticator

This might be better on the dev list, but the Authenticator and Authorizer interfaces should let you drop a jar in the classpath and turn them on in the yaml - you shouldn’t NEED to change much code, but that doesn’t mean the the interfaces have considered your use case. If the interfaces are

server connection in authenticator

Hello guys, We are building up an authenticator using certificates. So far we came up with a solution, but implies changing some files in Cassandra code base in order to have the connection in the new Authenticator. So, here are my questions: * how are you guys doing this? * is it possible to
