James E. King, III commented on THRIFT-1915:
--------------------------------------------
If someone implements a multiplex listener in version 1.0 and updates their
server, can the server still accept non-multiplexed traffic for backwards
compatibility from older clients? If not, does that meet the requirements for
thrift backwards compatibility (are there any)? I agree, the ~250 channels is
not ideal, however it was a better solution than changing the protocol to
version 2 and adding more space for it. The name is flexible, I like that. It
will take up more space on the wire than a single byte and require more
processing to decode (strchr + substr) than hitting a lookup table based on a
slot number. All acceptable trace-offs in either direction if product
requirements are met. Does this patch work to address two-way communications
over the single established connection? The ability for the client to register
as a service handler and for the server to do push notifications to the client
over a service is a long-sought-for feature. This requires abstracting the
endpoint so that either side can be a service handler. Was that discussed as a
post-1.0 feature perhaps? Thanks.
