             Summary: Add support to "unset" JSON fields in prepared statements
                 Key: CASSANDRA-11424
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-11424
             Project: Cassandra
          Issue Type: Bug
            Reporter: Ralf Steppacher


CASSANDRA-7304 introduced the ability to distinguish between {{NULL}} and {{UNSET}} prepared statement parameters.

When inserting JSON objects it is not possible to profit from this as a prepared statement only has one parameter that is bound to the JSON object as a whole. There is no way to control {{NULL}} vs {{UNSET}} behavior for columns omitted from the JSON object.

Please extend on CASSANDRA-7304 to include JSON support.

(My personal requirement is to be able to insert JSON objects with optional fields without incurring the overhead of creating a tombstone of every column not covered by the JSON object upon initial(!) insert.)
