gRPC protocol head for Cadence frontend handler #2345

Closed samarabbas closed 2 years ago

samarabbas commented 5 years ago

Currently Cadence defines frontend API as thrift and uses yarpc over tchannel for communication between external clients and Cadence service. This issue is to expose gRPC protocol head for the public API and define protobuff definitions for all public API. Initially this API implementation could just proxy API calls to thrift API handlers.

Hi, do we have any ETA on this? Thanks!

We are targeting alpha release of the gRPC version of Cadence in February.

CalPeterWu commented 4 years ago

@mfateev Great, thanks Maxim!

BartXZX commented 4 years ago

Does this mean that Cadence workers will be able to communicate with the frontend over gRPC?

We need this to be able to run workers outside of the Cadence cluster.

mfateev commented 4 years ago

@BartXZX Yes. The workers are going to talk to the cluster through gRPC.

Thanks! Is temporal a complete replacement for cadence right now with the MIT license?

samarabbas commented 3 years ago

Temporal is Open Source with MIT license. Please refer to stackoverflow post for a more complete comparison between the two open source projects.
