Subject [jira] [Commented] (CASSANDRA-11521) Implement streaming for bulk read requests
Date Fri, 15 Jul 2016 10:11:20 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15379166#comment-15379166

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

Here is quick update. Progress has been somewhat slow in the last week due to other tasks.
Nonetheless, the unit and dtests are now passing. I've repeated the benchmark and unfortunately
there is a performance degradation of about 25% compared to the proof of concept. I've started
investigating this but I haven't identified the exact reason for it. I'm attaching the JFR
profiles for client and server in case anyone is interested in taking a look: [^final-patch-jfr-profiles-1.zip].

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