does thrift support async client for ruby?

[T Vinod Gupta <tv...@readypulse.com>]

does anyone know if thrift (0.6.0 or 0.8.0) support async/non-blocking ruby
client? if yes, how does the client get the return results?

in my setup, the client calls the service with a request that can take some
time for the server to respond to. so how can this be made non-blocking
wherein the client is gets notified with the results when the call really
returns?

thanks

There is an open issue on jira to add support for EventMachine:
https://issues.apache.org/jira/browse/THRIFT-146

The issue contains a patch series that you could apply to get a
non-blocking ruby client.

In rereading your original post, I think that I misread it initially. I
think you're asking for server->client notifications, which we also don't
support. If you don't want the client to wait, the simplest thing you can
do is to have two methods - one to make a request that returns nothing, and
another that gets the result if there is one. Then the client can poll on
whatever appropriate interval.

If you REALLY need notification based updates instead of polling, then the
best thing to do would be to actually have your clients run a Thrift server
as well and make the server know how to contact them with completion
messages. This is complicated, and you're unfortunately on your own.

thanks Bryan.
Can you elaborate little more on what you meant by using threads to achieve
this? did you mean spawning multiple threads in ruby to get the data and
coalescing them somehow?

thanks

I don't think we've implemented an async client in ruby thrift.

The usual pattern is to use threads to achieve this sort of async behavior.
