Subject Logging Cassandra Reads/Writes
Date Tue, 09 Jul 2013 19:25:59 GMT

In a quorum read, my understanding is that Cassandra gets a digest of the
object to be read from all nodes, and then chooses the fastest node for
retrieving the data (if the quorum is met). 

1) Is it possible to log which node provides the real data in a read

2) Also, is it possible to log the different delays involved in each
operation-- for example, 0.1 seconds to get digests from all nodes, 1 second
to transfer data, etc.?
