Sylvain Lebresne updated CASSANDRA-9745:
    Summary: Better validation for values  (was: Allow validating values through a UDF)

> Better validation for values
> ----------------------------
>                 Key: CASSANDRA-9745
>                 URL:
>             Project: Cassandra
>          Issue Type: New Feature
>            Reporter: Sylvain Lebresne
>            Priority: Minor
>             Fix For: 3.x
> The only server side validation we do for values is currently that they match their type.
Now that we have UDFs, we could allow to optionally specify a (boolean) value validation function
on a per-column basis. This would give us a pretty generic way of validating value, which
sounds useful to me.
> Once we have that, we could even add some syntactic sugar for some common type of validations,
like {{v int[0..100]}} for numbers between 0 and 100, or {{v text[20]}} for a string that
is not longer than 20, ... That's more of a follow up however.
