> PK indices in 'Prepared' response can overflow
> ----------------------------------------------

> Key: CASSANDRA-13193
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13193
> Project: Cassandra
> Issue Type: Bug
> Reporter: Olivier Michallat
> Priority: Minor
>
> CASSANDRA-7660 added PK indices to the {{Prepared}} response. They are
> encoded as shorts.
> It's possible to prepare a query with more than 32768 placeholders (the hard
> limit is 64K). For example, we sometimes see users running IN queries with
> thousands of elements (a bad practice of course, but still possible).
> When a PK component is present after the 32768th position, the PK index
> overflows and a negative value is returned. This can throw off clients if
> they're not prepared to handle it. For example, the Java driver currently
> accepts the response, but will fail much later if you try to compute a bound
> statement's routing key.
> Failing fast would be safer here, the prepare query should error out if we
> detect a PK index overflow.
