Weekly hangout notes
Not sure if we ever shared this, but here is the weekly hangout notes that
includes what we talked about today:

Participants: Harri Kinnunen, Jacques Nadeau, Timothy Chen, Francisco
Freire, Ben Becker, Alec Ten Harmsel, Steven Philips


   Jacques working on better integration of schema with Optiq/JDBC,
   Streaming aggregate, improving basic optimizer

   Tim worked on JSONStorageEngine, and started on Limit Opereator

   Ben worked on MergeSort on single record batches, seeing bugs in
   multiple schema changes

   Lisen is looking into client reconnection problem, working on Semi-join
   (Bit vector) or Hash join based on Off-heap hash map index. Jacques said he
   worked on a Concurrent hashmap using off-heap memory and will try to dig
   that up. Can also look at Columnar sort using Radix sort.

   Steven Phillips worked on packaging, creating deb, rpm packages

   Harri continues to work on architecture documentation, and installation

   Watch out for batches materialization, where Jacques found issues that
   after serialization value vector read expressions are pointing to outgoing
   batch column info instead of incoming

   Jira has issues tagged with Alpha, and please verify the issues and
   add/remove any as fit

   Still need to discuss more about Alpha messaging next week.

For people interested in contributing to Drill and/or wants to know the
latest development progress, we hangout every tuesday morning 9am PST for
discussions and updates.
