Jonathan Ellis commented on CASSANDRA-768:
------------------------------------------
This is not a good fit for cassandra.
> "safe mode" for nodes so that they do not participate in reads until hinted
> handoff is complete

> Key: CASSANDRA-768
> URL: https://issues.apache.org/jira/browse/CASSANDRA-768
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Reporter: Robert Coli
> Priority: Minor
>
> Summary :
> When using ConsistencyLevel.ONE for read performance reasons, stale data can
> be served by a node which has been temporarily unavailable. When a node has
> been unavailable for some time and other nodes have queued updates for it via
> hinted handoff, it would be operationally useful to be able to configure the
> node to not participate in read traffic until the hinted handoff process is
> complete. A "safe mode" would offer operators a greater consistency guarantee
> across all nodes without the per-read performance tradeoff of a higher
> ConsistencyLevel. This "safe mode" concept might also be applicable to nodes
> undergoing "repair" processes, for example in the case of on-disk data
> corruption or loss.
