Subject [jira] [Commented] (CASSANDRA-6833) Add json data type
Date Tue, 11 Mar 2014 21:00:46 GMT


Aleksey Yeschenko commented on CASSANDRA-6833:

bq. A timestamp is "just" a bigint by that reasoning. Should we not support that extra layer
of meaning either?

It's about messaging. Having a JSON type, even if it's really a blob with some extra validation,
sends a message that putting JSON blobs in cells if OK, where in reality it's more often NOT
OK. You might not see it that way, but users will. We should not be encouraging it.

The risk of poisonous message vs. the extremely minor benefit of the type (blob with validation)
makes this issue a no-brainer won't fix, imo.

> While recognizing that UDT (CASSANDRA-5590) is the Right Way to store hierarchical data
in C*, it can still be useful to store json blobs as text.  Adding a json type would allow
validating that data.  (And adding formatting support in cqlsh?)
