Alex P commented on CASSANDRA-6833:
-----------------------------------
Besides [~benedict]'s example, this might be quite useful for scenarios where
an app needs to ingest a lot of JSONish data that would be processed later
(think sensor data). At ingestion time, only minimal validation would be
needed.
A possibly interesting extension of the feature described would be to allow
some sort of extensible validation interface. By implementing an interface (a
la Triggers), one could add a bit of a smarter validation (e.g. does this
object has a name attribute, is the email attribute well formed, etc.).

> 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?)
