Hi

We've (AssessTech) have been using thrift for the last 2 years or so.

I want to know who is using thrift, what are typical problems faced by

We have written a custom discovery lay based on bonjour which allows us to
route client requests to an applicable service instance.

Our thrift servers manage quite a hefty load, and so far we've never had any
issues with it.

In terms is issues 'using' Thrift, the only issues have come as a result of
language limitations which have guided our use of thrift.

We use the java, php and cocoa (on osx and iOS) bindings.

Cheers,

OH HAI!

We at www.doat.com use it to connect a few independent modules in out
backend.

The problems we've had weren't so much due to thrift, but rather due to
language limitations.
Our core back end server is written in python, which has a limitation of a
single CPU for all threads in one process.
To overcome this, we wrote and contributed back TProcessPoolServer - a
pre-forked, process pool based server that uses many worker processes in one
wrapper server process.
This has increased our performance considerably.

Another C++ based server we had did not share these issues as we used a non
blocking server.

We are also using PHP based clients.

and I also want to know how to load balance thrift services

We use Pen to load balance the clients. Each front end machine has its own
load balancer that gets automatically configured with the available
backends.
So from the perspective of the client code, it is just connecting to
127.0.0.1:$someport

We (OpenX) use it extensively.

I don't remember encountering many problems (we started using it late in
2008). We use the Java, Erlang, and PHP libraries.

We're using HAProxy to load-balance between a pool of back-ends. I've
written some libraries for Java and Erlang that make it easy to re-use
connections and get dynamically resizing pools based on traffic volumes and
back-end response times.

HTH,
Joel
