Jens Geyer commented on THRIFT-5164:
------------------------------------

I'd also love to have some sort of highlevel design document to make it easier 
for other language maintainers to implement the concept. The general idea is to 
have all languages aligned as much as possible, so sooner or later this will 
find its way into other language bindings. Hence, having some conceptial 
outline would be awesome. I would even tend to say required ...

> We (Reddit) recently implemented TProcessor level middleware support in our 
> Baseplate.go library, and we think that our implementation is generic enough 
> that it might make sense to contribute that into the thrift library. The 
> related implementation are all in this file: 
> https://github.com/reddit/baseplate.go/blob/4225e42dc8dde56b222ac7ea3a4ff63aa726f6a6/thriftbp/middlewares.go

>  is an example of how a tracing middleware is implemented.
> If we think that's a good idea, then we can contribute that into thrift repo 
> (with renames, of course). One implementation detail I'm not sure is that 
> whether we want to expand the TProcessor interface to also include 
> ProcessorMap and AddToProcessorMap, or do we want to keep the two iinterfaces 
> separate.
