------------------------------------
Summary: Batch multiple range requests that are going to the same
replica
Key: CASSANDRA-7982
URL: https://issues.apache.org/jira/browse/CASSANDRA-7982
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jay Patel
Assignee: Jay Patel
Fix For: 3.0
In case of VNode and secondary index query, coordinator sends multiple range
requests to the same replica. For example, in the attached tracing session
(output1.txt), coordinator(192.168.51.22) sends multiple requests to
192.168.51.25. Why can't we batch all the requests to the same replica to avoid
multiple round trips? I think this is not the issue with non-vnode cluster
where each node has one big range (+ replica ranges), instead of many small
ranges.
