Subject [jira] Created: (CASSANDRA-241) move daemon to framed transport (thrift)
Date Fri, 19 Jun 2009 19:44:07 GMT
move daemon to framed transport (thrift)
----------------------------------------

                 Key: CASSANDRA-241
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-241
             Project: Cassandra
          Issue Type: Bug
    Affects Versions: 0.4
            Reporter: Eric Evans
            Assignee: Eric Evans
             Fix For: 0.4


The framed transports in thrift wrap the underlying transport to prepend the message size
as a 4 byte value.  There are purported benefits to buffering, but the main purpose of these
wrappers is to allow non-blocking servers to perform reads without deserialization. Of course,
if the server transport is framed, the client's must be as well, and vice versa, (framed and
non-framed transports are incompatible). 

CassandraDaemon is currently a threaded server with the default transport, I believe we should
change it to being framed, for compatibility with non-blocking clients (this actually came
up during an attempt to use a Twisted client).

This will break all existing client apps, (even if fixing them is trivial).
