In general streaming data via websocket has its own problem with respect to speed. The abstractions being json, the data is parsed at your end and at client end making the processing of data very slow. If I have 200 instrument,even with distributed processing the time taken to parse/process one tick of 200 instruments is immense. My purpose of this request is to find an alternative to websocket which is atleast a bit faster an therefore gRPC comes to my mind. @sujith and @Kailash let me know your thoughts.
