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.
