Beinan has been very helpful on the community and Presto foundation side - with presentations on higher level introductions to Presto as well as deeper tech talk sessions. In addition, he has been very helpful with PR reviews on connectors as well as answering user questions and troubleshooting on slack and other community channels. 

Thank you Beinan!

GSOC 2021

Nezih Yigitbasi
 

Hey folks, 
Google Summer of Code is approaching, and it would be great if we can have some project proposals out there. If you have any project ideas, please put together a project proposal and Gale (our program manager) will help submit that proposal. The proposal can be about adding new features, connectors, UI improvements, perf improvements, etc. anything that you think of that can be useful for Presto. There will be mentorship needed while the students work on these projects, so some time investment will be needed (probably a few hours per week). There is a great GSOC mentor guide which you can take a look here for more info.

As additional examples. here is the CNCF template & some example projects that can give you an idea. Similarly, here is GraphQL's application from GSOC 2020. Applications are open Jan 29 - Feb 19. 

Thanks!

Subject: [presto-tsc] Nominating Ying Su as new committer





Dear TSC members,





I would like to nominate Ying Su as a committer. Ying has been working on Presto for almost 3 years. She had contributed 200 commits with 20K+ lines of code.





She primarily worked on execution and performance optimization. Some of her highlights are:







  • Optimize repartition, which brought 2-3x CPU reduction on PartitionedOutputOperator (Blog Post)

    and 6x memory reduction.


  • Optimize Unnest, which brought up to 20x CPU reduction on UnnestOperator in Facebook workload (Blog Post)


  • Scan optimizations that brought additional 3 -17% efficiency through vectorization and batch processing on top of Aria Scan optimizations.


  • Many performance improvements in projection, map / array functions, etc.


  • Many memory / GC fixes, etc


In addition to her contribution, she also provided valuable feedbacks on others’ work related to execution / performance improvements. I think it’s safe to say that Presto would not be as good without her contributions.



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 Ying

as a committer. 





Thanks!
