T Jake Luciani commented on CASSANDRA-2388:
-------------------------------------------
bq. what is the lost performance of writing to the furthest node that's within
the same datacenter?
The benefit is really the DynamicSnitch. if a node it slow due to compaction
then this would avoid sending requests there...
bq. public String[] sort_endpoints_by_proximity(String endpoint, String[]
endpoints, boolean restrictToSameDC)
I don't think it makes sense to send the client endpoint to this call since the
endpoint might not be a cassandra node. It's a reasonable assumption that the
endpoint it's talking to is local enough to the client to use that.
> ColumnFamilyRecordReader fails for a given split because a host is down, even
> if records could reasonably be read from other replica.
