Cassandra driver 4 changed quite a lot, and now creating tables can take quite a while.
Consider disabling schema metadata on CqlSession while performing SchemaAction to reduce the schema creation time
cqlSession.setSchemaMetadataEnabled(false);
performSchemaAction();
//null to use driver configuration and refresh schema metadata if required
cqlSession.setSchemaMetadataEnabled(null);
