Instead of having a separate /scheduler/events endpoint with a top level Subscribe protobuf, could we just have one /scheduler/call endpoint and have a SUBSCRIBE Call? I prefer this because: (1) There is a single endpoint / Call interface for the scheduler. (2) We don't have to have the "special" Subscribe top level protobuf. (3) When we move to HTTP/2, we don't have to change anything, we can just tell people that they are now free to use a *single* connection for all calls. For HTTP/1.1, we tell people that they must make the streaming Subscribe call on a standalone connection. Was the motivation for separating the Subscribe call out to a separate endpoint to try to make the connection management more obvious? People already have to think about connection management regardless of having /scheduler/events as a different path. Are there any major reasons I'm missing for not consolidating on one endpoint? - Ben Mahler On March 31, 2015, 12:10 a.m., Vinod Kone wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
