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!

Hi Gale,

I'd like to nominate +Nezih Yigitbasi for this role. I think he did a great job this past year and led the TSC very well. Next year will also be critical with upcoming changes to TSC structure (committers v/s TSC members), community engagement ramp-up, new companies joining, technical roadmap changes, etc., and I think Nezih is very well equipped to lead the TSC through these challenges.

Best,

Girish
