Jonathan Ellis commented on CASSANDRA-5886:
-------------------------------------------
That reasoning makes sense to me.
> Provide a propagation guarantee for DDL queries execution
> ---------------------------------------------------------
>
> Key: CASSANDRA-5886
> URL: https://issues.apache.org/jira/browse/CASSANDRA-5886
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Michaël Figuière
> Priority: Minor
>
> Currently schema modifications are not guaranteed to be propagated when the
> DDL statement's response reach the client. While this is not a drama, it
> appears to be annoying when writing integration tests for an application for
> instance. Additionally this behaviour gives a feel of brittleness to
> newcomers who meet a "Table does not exist" error on a table that they've
> just created.
> A possible workaround would be for the coordinator to wait for at least one
> replica of each partition to acknowledge a DDL query. Then when a node meets
> a schema error on a DML query it could contact the other replicas for one of
> the token it owns to check for schema updates.
> Doing so would make DDL queries and DML queries with schema errors slower but
> it doesn't matter as performances of the former are not critical (and the
> response time would still be reasonable as we wait only for the fastest
> replica of each partition to answer) and the latter are not expected to
> happen in stable production environments.
> The guarantee would not be absolute as all of the nodes for a given partition
> might be down/not answer on time. But doing so we would make the error much
> more unlikely to happen. And we'll always have the possibility to increase
> the amount of partitions to contact in the case of DML schema errors...
