Description
In our performance tests for insert vertices/edges, and queries with Cassandra v3.11.3, the CQL driver is slower than the deprecated astyanax/thrift driver. It would be great to look into ways to improve CQL performance since it seems the recommended driver moving forward.

Research direction
Start with the performance tests for inserting vertices and edges and running queries against Cassandra v3.11.3, comparing the CQL driver with the deprecated astyanax/thrift driver. Investigate the reported performance gap and define completion as measurable CQL performance improvements relative to the existing comparison.
