You also can have Apache ZooKeeper on top of thrift to manage failover

You will have to write your own wrapper for that.

As far as I know, Thrift has no such aggregation service and in my
opinion
there is a reason for that too:

1) What if a Server fails to respond to the request? How does the
Service
react? It will be very specific to what kind of behavior you want to
achieve.
 Example: Ignore the request which is taking a lot of time? All the
other
requests become invalid or not.
