Subject [jira] Commented: (AVRO-271) InProcessTranceiver: connect RPCs without going through any sockets
Date Thu, 31 Dec 2009 18:37:29 GMT

    [ https://issues.apache.org/jira/browse/AVRO-271?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12795636#action_12795636

Doug Cutting commented on AVRO-271:

> the problem is that readBuffers() and writeBuffers() shouldn't be public.

These were intended to be used by servers to read requests and write responses.  But my hope
of writing a generic server that's passed a Transceiver hasn't worked out in practice, even
when servers process requests synchronously, and it definitely wouldn't work for an async
server.  So removing readBuffers() and writeBuffers() altogether might make sense, and declaring
that Transceiver is for client-side use only.

InProcessTransceiver can simply implement transceive() to directly invoke Responder#respond().

Also, what do you think of renaming InProcessTransceiver to be LocalTransceiver?

> For testing (both Avro itself, and code that uses
> Avro servers) it's sometimes handy to connect the RPCs without
> even a socket. This implementation of a Transceiver does just that.
> (This can, for users, both avoid the overhead of using sockets, and,

> and server code in one thread.)
