Subject [jira] [Commented] (CASSANDRA-3590) Use multiple connection to share the OutboutTCPConnection
Date Fri, 09 Dec 2011 04:21:46 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3590?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13165832#comment-13165832

Vijay commented on CASSANDRA-3590:
----------------------------------

I think more in parallel after retrieving from the queue are always better, specially with
all kinds of delay's introduced by the networks across the DC's/Public internet can make it
un-predictable, i will do some micro benchmark soon. Atleast will help the cases where there
frequent disconnects and we wont need to wait till the connection is established again.

> Currently there is one connection between any given host to another host in the cluster,
the problem with this is:
> 1) This can become a bottleneck in some cases where the latencies are higher.
> 2) When a connection is dropped we also drop the queue and recreate a new one and hence
the messages can be lost (Currently hints will take care of it and clients also can retry)
> by making it a configurable option to configure the number of connections and also making
the queue common to those connections the above 2 issues can be resolved.
