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.
