Subject [jira] [Commented] (CASSANDRA-3017) add a Message size limit
Date Tue, 13 Nov 2012 02:03:12 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-3017?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13495852#comment-13495852

Kirk True commented on CASSANDRA-3017:
--------------------------------------

I'd love to research the relationship between Thrift and intra-cluster messages. Can you provide
a sentence or two about exactly what that entails? 

* Do I simply measure this via a series of get requests of varying column slices and column
data size, or does it need to be exhaustive for every message type?
* Can the request sizes be gleaned with more logging or do I need to bust out Wireshark?
* Is the data size for inter-node messages constant with respect to the initial Thrift message
or is some kind of compression in the mix?

> We protect the server from allocating huge buffers for malformed message with the Thrift
frame size (CASSANDRA-475).  But we don't have similar protection for the inter-node Message
objects.
> Adding this would be good to deal with malicious adversaries as well as a malfunctioning
cluster participant.
