Subject Re: [DISCUSS] KIP-104: Granular Sensors for Streams
Date Tue, 03 Jan 2017 19:12:01 GMT
Thanks for the proposed KIP. Overall LGTM.

A few comments:

1. "at the granularity of each processor node, in the addition to the
global rate"

I think you also add one sensor at the granularity of tasks, "Skipped
records sensor in StreamTask" right?

2. From PR 1446 it seems you have also added a couple of APIs for allowing
users to register arbitrary sensors via `StreamsMetrics`, could you also
describe the changes and when / how users are expected to use them as well?

3. Could you also list the added overloaded APIs for throughput sensors as
well as with the recordLevel parameters, and mention what will be the
default values for those added parameters in the existing API functions?
