Subject Re: HAWQ Perfomance.

Strong +1 on this.

Performance is one of the reasons why our customers choose HAWQ, the
existing leading performance might come from C implementation and Postgres
implementation I think. Hawq will definitely focus on some performance
improvement but frankly speaking plan/roadmap should be shaped and
discussed in detail like this thread. Below are some of our
beforehand consideration and to-do list:

  - Codegen tech to optimize executor efficiency.
  - Data-skipping tech to optimize I/O performance.
  - Optimize external table access, especially PXF.
  - Some vectorized refactor.
  - Optimize data locality.
  - Optimize distributed resource organization and management.
  - Optimize communication module of interconnect.
  - Gpus, SSDs
  - ...

We are running performance tests in several cluster environment for HAWQ
every week and continue paying attention to latest performance update from
our competitor and research paper. But we need some more guys joining us to
be focused on performance feature. We are very very welcome that some
developers from HAWQ open-source community to be a member of us in
performance part.
