James E. King, III updated THRIFT-66:
-------------------------------------
Attachment: Thrift Endpoints and Channels.vsd
Visio diagram showing how endpoints and channels work - a concept to replace
the existing one-way communication mechanism. I have not marked this as meant
for inclusion yet, as there may be some changes before it is finalized. You
may need Visio 2010 to view it?
> Allow multiplexing multiple services over a single TCP connection

> Key: THRIFT-66

> Project: Thrift
> Issue Type: New Feature

> The current {{TServer}} implementations expose a single service on a port. If
> an application has many services many ports have to be opened. This is
> cumbersome because:
> - you have to document which service is available on which port, and
> remembering the port numbers is difficult
> - to prevent the overhead of connection setup on each call, a client has to
> maintain to many connections: at least one to each port
> - it requires opening many ports on a firewall if one is between the client
> and the server.
> By multiplexing multiple services on a single port the problems above are
> resolved:
> - instead of a port number a symbolic name can be assigned to a service
> - a client can maintain a small pool of connections to a single port
> - only one port has to be opened on the firewall
> The attached Java implementation simply wraps a normal {{CALL}} message with
> a (new) {{SERVICE_SELECTION}} message. It is not necessary to modify or wrap
> the response. No changes are needed to the generated classes. Only a new type
> of server is introduced, and an invocation handler for a dynamic proxy around
> the {{Client}} classes of services is provided for the client side. The
> implementation does not handle communication errors (invalid data, timeouts,
> etc.) yet.
