> Make CQL grammar more easily extensible
> ----------------------------------------
>
> Key: CASSANDRA-11372
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11372
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL
> Reporter: Mike Adamson
> Assignee: Mike Adamson
> Fix For: 3.6
>
>
> The CQL grammar ({{Cql.g}}) is currently a composite grammar and, as such, is
> not easy to extend.
> We now have a number of 3rd parties who are extending the grammar (custom
> index grammars, for example) and it would be helpful if the grammar could be
> split in a parser and lexer in order to make extension easier.
