Nominating Ariel Weisberg

Andrii Rosa
 

I would like to nominate Ariel Weisberg for both committer and TSC membership.

From the very first day working at Presto Ariel has been one of the most active members of the Presto open source community. He has made substantial contributions to establishing the Presto Foundation, defining community guidelines and building relations with other companies. Currently Ariel is also one of the most active Facebook engineers in the PrestoDB Slack who is actively engaging with the external Presto community by answering their questions, helping to resolve the issues they are facing, and connecting them with experts in a specific area if needed.

Ariel has reviewed 104 PR's with the total of 32109 LoC from 30 authors, 12 of which are external contributors from the community. Ariel provided code review and all required support to land Hive 3.0 integration, a large contribution from the community that had been a major blocker for broader Presto adoption.
Pull requests reviewed and accepted by Ariel meet the community standard. In those cases when Ariel didn't have enough context to provide a code review he has been able to identify area owners and loop them into the review process.

As his personal contributions Ariel:
  • Added support for more fine grained partitioning strategies to better handle skewed queries
  • Improved memory utilization reporting and memory limits enforcement
  • Optimized the memory footprint of RemoteExchangeOperator
  • Migrated CI from Travis to Github Actions when the project was blocked on Travis allowing us to save hundreds of thousands on CI and improving test runtime and stability
  • Restored the lost Docker containers used for product and integration testing and reenabled these tests on CI
  • Added the blog to the web site, solicited, edited, and reviewed many of the blog posts
  • Ensured the web site continues to run and deploy throughout various infrastructure changes
  • Maintained the GH organization memberships and permissions and other integrations

Please respond whether you support Ariel as a committer or a TSC member or both.

Subject: [presto-tsc] Github Status Checks

 

Hello,

 

As mentioned in the TSC meeting today, I’d like to enable the Github status checks requirement to the master branch, which means status checks must pass before a PR can be merged.  This is to prevent accidental merge of a failing test into the master branch, or to prevent known failing tests from affecting other PRs.  If there’s unrelated flaky tests, then the idea is we should fix these tests or mark them as disabled.

 

Documentation on Github status checks are here: https://docs.github.com/en/github/administering-a-repository/about-protected-branches#require-status-checks-before-merging

 

Please give this a +1 if you agree that code should not be merged with known test failures.

 

Thanks

Tim

Hello,

 

We would like to get started with a formation of a new working group under the technical charter of Presto.  The purpose of this working group is to guide the development and implementation of a conformance program which will aim to define what it is a conforming Presto implementation, develop an automated test suite to verify if a an implementation is truly in conformance, and creating a process for engines to verify their conformance.

 

To establish this, the working group will be meeting regularly, posting updates to the TSC on a regular basis, and meeting regularly to help define some of the goals listed above.  This working group will be available for anyone to attend.

 

I have attached a new template to get started with the formation of this working group.  This establishes how the working group will operate, and it requires an approval from voting members of the TSC.

 

https://github.com/prestodb/tsc/pull/62

 

Please leave any feedback you have for this template by requesting changes on the PR.  Once consensus is reached and it’s been approved, we’ll then proceed to collect nominations for a chair for the working group.  Then, once a chair has been elected from the nominees, the working group will commence and begin working on solving the problems outlined above.

 

In the meantime, a mailing list for this group has been created.  It’s available here:

 

https://lists.prestodb.io/g/presto-conformance-wg

 

If you’re interested in joining this effort and helping to solve the questions outlined above, please add yourself to this list.  It’s also not necessary to be a member of the TSC—anyone may join.

 

Thank you

Apparently he’s already on this list ☺.

Gale- can you add him as a committer on github?  Also, I believe Beinan still needs to be added as well.

Subject: [presto-tsc] Nominating James Petty as new committer

Hi TSC members,

 

I'd like to nominate James Petty as a committer. James has been working on Presto for a little over 2 years, first as part of the AWS Athena team and now as a member of the EMR performance team. Some of his contribution highlights include:


* Reducing sources of lock contention throughout the engine (prestodb#15509, prestodb#15477)

* Reducing coordinator heap pressure from Glue metastore partitions (prestodb#15389)

* Various bug fixes, including a fix for a long standing accounting issue with memory revoking (prestodb#15569)

* Implementing spill to disk compression and encryption (prestodb#12617)

* making query result GZIP compression configurable (prestodb#15393)


The full list of his commits can be found here: https://github.com/prestodb/presto/commits?author=pettyjamesm

Per the TSC charter "A Contributor may become a Committer by a majority approval of the existing Committers.", therefore, each TSC member has one vote to cast. Please reply with +1/-1 if you approve/disapprove onboarding James as a committer. 

 

Thanks,

Shixuan
