Subject [jira] [Updated] (CASSANDRA-5436) Binary protocol versioning
Date Wed, 24 Apr 2013 06:19:16 GMT

     [ https://issues.apache.org/jira/browse/CASSANDRA-5436?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Marcus Eriksson updated CASSANDRA-5436:
---------------------------------------

    Attachment: 0001-CASSANDRA-5436-add-basic-protocol-versioning.patch

Adds the version when exception is caught

for now perhaps it is enough to just let too new clients retry with lower version if they
get an ProtocolException on connection

> There should be a way to version the binary protocol, CASSANDRA-5349 adds a message that
breaks compatibility (QueryMessage) and the ticket half-handles versioning - it allows old
clients to connect and execute queries (by always replying in the same version as the message
sent by the client), it does not allow new clients to connect to old servers though.
