Subject [jira] [Commented] (CASSANDRA-2819) Split rpc timeout for read and write ops
Date Fri, 01 Jul 2011 18:12:28 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-2819?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13058684#comment-13058684
] 

Melvin Wang commented on CASSANDRA-2819:
----------------------------------------

how about add the creation timestamp to the header of the message? MDT is executed nearly
immediately after it is created. Thus the construction time of MDT is too close to the checkpoint
we have in run(). I am just concerned with the effectiveness of the current logic in MDT,
although I am not sure about the consequences of adding 4 bytes to all the messages we created.

> Given the vastly different latency characteristics of reads and writes, it makes sense
for them to have independent rpc timeouts internally.
