Amareshwari Sriramadasu commented on LENS-124:
----------------------------------------------
Here are some comments :
I did not understand the response header of
POST on /schedules : queryapi/schedule/123 : Is this more a redirect?
I think we are missing some more requirements, I'm putting them down here :
# Schedule spec can be a series of queries. For example : Schedule spec can
consist of
Q1 : query1; Q2 : query2; Q3 : query3 : where Q2 and Q3 might access of output
from Q1.
# Schedule spec can be an ML train or test
Here is some code which was sitting in a branch, on
https://github.com/InMobi/grill/tree/scheduler/ before lens incubation. Some of
the api has been reviewed and put out there. We can refer them :
