Sylvain Lebresne updated CASSANDRA-8969:
----------------------------------------
Attachment: 8969.txt
Attaching a patch that describe with a bit more detail what the rpc timeouts
are useful for (and hence why you don't want to set them too high).
When you mention memory building up, I assume it's a reference to reads going
on for too long reading tons of stuffs? In which case I'll note that before
CASSANDRA-7392 the rpc timeouts weren't really helping with that, and so the
attached patch is really only meant for trunk (it's partly false for earlier
releases).
> Add indication in cassandra.yaml that rpc timeouts going too high will cause
> memory build up

> It would be helpful to communicate that setting the rpc timeouts too high may
> cause memory problems on the server as it can become overloaded and has to
> retain the in flight requests in memory. I'll get this done but just adding
> the ticket as a placeholder for memory.
