Welcome new Calcite commiters: Aman Sinha, Jesús Camacho-Rodríguez, Jingfeng Ni, John Pullokkaran and Nick Dimiduk
I am very pleased to announce that the Project Management Committee
(PMC) of Apache Calcite has asked Aman Sinha, Jesús Camacho-Rodríguez,
Jingfeng Ni, John Pullokkaran and Nick Dimiduk to become a committers,
and that they have each accepted.
Aman and Jinfeng are active Drill committers. They have been adding
functionality to Calcite for Drill's needs, including Calcite's
handling of collations, and validation of the ANY type, and recently
have undertaken the challenging task of getting Drill onto a more
recent version of Calcite.
Jesus and John are active Hive committers. They have made significant
contributions to Calcite's rule set and cost model.
Nick is a committer on Phoenix and HBase. Over a short period of time
he has made major improvements to Avatica's server, RPC protocol, and
thin JDBC client.
Welcome all! It would be great if you would each say a few words to
introduce yourself.
Julian
On behalf of the Apache Calcite PPMC

Thanks for the opportunity to contribute to Calcite.
I work on Hive compiler, Optimizer.
In past I worked on OLTP engine, Streaming SQL, Federated DB Engine.
Looking forward to further involvement with Calcite.
Thanks
John

Thanks to Julian and the PPMC members for this opportunity!
Currently I am working on the Apache Hive's query optimizer, where we are
focusing on closing some gaps that will allow us to take fully advantage
of Calcite's features in the near future.
I hold a PhD degree that focused on investigating efficient techniques for
large-scale Web data management. During its development, I had the chance
to work on other Apache projects such as Pig or Flink.
My interests include query optimization, semi-structured data management,
and large-scale data management programming models.
I really enjoy contributing to Calcite, and I am looking forward to
getting involved even further!
Thanks,
Jesús

Thank you Calcite PPMC for this opportunity!
I worked in both query optimization / execution areas in Apache Drill. My
main interests are to extend Calcite to build efficient distributed query
plan, and to support query semantics checking / transformation in
schema-less system. Prior to Drill, I had work experience in IBM DB2 query
optimization.
I'm happy to contribute to Calcite, and am looking forward to working
closely with Calcite community.

Thanks Julian, Jacques and others for this opportunity. As requested,
here's a brief introduction: I work on various query
processing/optimization areas of Apache Drill. My primary interests are
mainly in making the core SQL operators perform better - either through the
optimizer or through executor or both. In the past I have worked on MPP
databases and an OLAP engine. I look forward to working with everyone in
this community to making Calcite a great query optimizer.

Thanks a lot PPMC! I'm happy to contribute and in particular push Avatica
to it's online latency limits via Apache Phoenix ;)
