This page describes compatibility between the Apache Cassandra GoCQL driver and DSE, HCD, Astra DB, and open-source Cassandra.
The Apache Software Foundation maintains the Cassandra GoCQL driver (gocql) 
GoCQL compatibility
GoCQL is compatible with Astra DB, DSE, HCD, and open-source Cassandra.
For information about specific versions of Go and Apache Cassandra supported by GoCQL, see Supported Versions in the GoCQL documentation.
GoCQL 2.x
GoCQL version 2.0 introduced breaking changes and new features, including support for the Apache Cassandra 5.x built-in vector type. Earlier versions of GoCQL don’t support the vector type.

The gocql-astra package isn’t compatible with GoCQL 2.0.
