Subject [jira] [Commented] (CASSANDRA-11521) Implement streaming for bulk read requests
Date Mon, 11 Apr 2016 03:51:25 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15234461#comment-15234461

Stefania commented on CASSANDRA-11521:
--------------------------------------

I like this suggested approach; it has many advantages, as already pointed out above. I will
prototype it and then compare performance with the existing "streaming" prototype. 

I have created CASSANDRA-11542, so we can actually compare with HDFS performance as well.
Once this benchmark is available, and the new approach has been prototyped, we will then have
4 measurements: 

* HDFS
* Cassandra trunk
* Cassandra with current "streaming" approach
* Cassandra with this new approach.

> Allow clients to stream data from a C* host, bypassing the coordination layer and eliminating
the need to query individual pages one by one.
