Subject [jira] [Commented] (CASSANDRA-11424) Option to leave omitted columns in INSERT JSON unset
Date Wed, 27 Jul 2016 07:06:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11424?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15395158#comment-15395158
] 

Sylvain Lebresne commented on CASSANDRA-11424:
----------------------------------------------

We're only committing bug fix to 2.2 at this point, and that's a minor improvement (anything
JSON related is minor in the sense that you can always work-around any problem/limitation
by not using the JSON syntax, which is merely a convenience), so no, we won't backport it,
sorry.

> 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.)
> {color}
