Subject [jira] [Commented] (CASSANDRA-3687) Local range scans are not run on the read stage
Date Mon, 02 Jan 2012 14:54:31 GMT


Jonathan Ellis commented on CASSANDRA-3687:

Look at SP.LocalReadRunnable for how to do this safely. Simplest fix would be to just continue
routing all range scans over MessagingService.

> Running directly on the client request/StorageProxy thread means we're now allowing one
range scan per thrift thread instead of one per read stage thread [which may be more, or less,
depending on thrift server mode], and it bypasses the "drop hopeless requests" overcapacity
protection built in there.
