Using gRPC with gevent

Question

I am using gRPC in a gevent monkey patched environment and I am seeing deadline exceeded for a deadline of 500ms. But the service responds in < 40ms. I am assuming this is due to the use of gevent, messing up the timing. But now where I have applied:

import grpc.experimental.gevent as grpc_gevent
grpc_gevent.init_gevent()

I am seeing DEADLINE_EXCEEDED even in my integration test.

Answer 1

I'm having the same problem. After looking at init_gevent, I found a sentence:

This must be called AFTER the python standard lib has been patched, but BEFORE creating and gRPC objects.

Try adding the import at the top:

from gevent import monkey
monkey.patch_all()
