Description

As per https://datastax-oss.atlassian.net/browse/SPARKC-503, that exception will be thrown by executeAsync() since at least 3.1.4 as executeAsync() is fully async, so it throws that exception if the driver-side pool is busy. 

This improvement has greatly improved the peek throughput of our Cassandra Sink Connector. It also allowed us to get all the benefits of the latest driver version.

I would like to contribute this feature back upstream.
