Tyler Hobbs updated CASSANDRA-7660:
-----------------------------------
Attachment: 7660-trunk.txt
The attached patch (and
[branch|https://github.com/thobbs/cassandra/tree/CASSANDRA-7660]) adds a new
field to the metadata in Prepared responses. The native protocol document has
been updated in the patch, so I'll avoid describing it in detail here.
I also have a branch of the python driver that adds support for this feature:
https://github.com/thobbs/python-driver/tree/CASSANDRA-7660-support.

> Currently, when native protocol drivers prepare statements, they need to
> check their internal representation of the schema to determine which, if any,
> of the columns are part of the partition key. If the native protocol
> response indicated this, it would remove the drivers' dependency on having an
> internal representation of the schema when preparing statements.
> This would need to go in the v4 protocol.
