Jeremy Hanna updated CASSANDRA-8754:
------------------------------------
Labels: LWT ponies (was: ponies)
> Required consistency level
> --------------------------
>
> Key: CASSANDRA-8754
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8754
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Ryan Svihla
> Priority: Major
> Labels: LWT, ponies
>
> Idea is to prevent a query based on a consistency level not being met. For
> example we can specify that all queries should be at least CL LOCAL_QUORUM.
> Lots of users struggle with getting all their dev teams on board with
> consistency levels and all the ramifications. The normal solution for this
> has traditionally to build a service in front of Cassandra that the entire
> dev team accesses. However, this has proven challenging for some
> organizations to do correctly, and I think an easier approach would be to
> require a given consistency level as a matter of enforced policy in the
> database.
> I'm open for where this belongs. The most flexible approach is at a table
> level, however I'm concerned this is potentially error prone and labor
> intensive. It could be a table attribute similar to compaction strategy.
> The simplest administratively is a cluster level, in say the cassandra.yaml
> The middle ground is at they keyspace level, the only downside I could
> foresee is keyspace explosion to fit involved minimum schemes. It could be a
> keyspace attribute such as replication strategy.
