> 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.
> {color:grey}
> (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.)
