[GitHub] [incubator-pinot] jackjlli opened a new pull request #6579: Decouple from yammer library
jackjlli opened a new pull request #6579:
URL: https://github.com/apache/incubator-pinot/pull/6579
## Description
This PR introduces factory pattern to decouple from yammer library, so that Pinot doesn't directly have to depend on yammer. This makes the codebase easy to integrate with other metric libraries, like dropwizard.
## Upgrade Notes
Does this PR prevent a zero down-time upgrade? (Assume upgrade order: Controller, Broker, Server, Minion)
* [ ] Yes (Please label as **<code>backward-incompat</code>**, and complete the section below on Release Notes)
Does this PR fix a zero-downtime upgrade introduced earlier?
* [ ] Yes (Please label this as **<code>backward-incompat</code>**, and complete the section below on Release Notes)
Does this PR otherwise need attention when creating release notes? Things to consider:
- New configuration options
- Deprecation of configurations
- Signature changes to public methods/interfaces
- New plugins added or old plugins removed
* [ ] Yes (Please label this PR as **<code>release-notes</code>** and complete the section on Release Notes)
## Release Notes
If you have tagged this as either backward-incompat or release-notes,
you MUST add text here that you would like to see appear in release notes of the
next release.
If you have a series of commits adding or enabling a feature, then
add this section only in final commit that marks the feature completed.
Refer to earlier release notes to see examples of text
## Documentation
If you have introduced a new feature or configuration, please add it to the documentation as well.

Review comment:
This `update` method in Timer interface is used in recording the time span in each of the query phases. I've updated the description in the next push. There are definitely more methods than just this one but this is the only one that's being used in pinot repo.

Review comment:
Nice! I think the next thing we can do (probably not in this PR) is that we can create pinot-metrics plugins and move yammer stuff to yammer-metrics and load it during runtime.

Review comment:
I checked the usage of `MetricProcessor` in Pinot existing code. It's used in Aggregate metrics like `AggregatedCounter`, `AggregatedMeter`, `AggregatedHistogram`. But since these metrics are legacy code, we actually don't need this interface any more. I've removed this interface in the next push.
