    - Serge reviewing existing draft prototype,
    - Jacek looking into c api for zookeeper,
      have some very early prototype working

      we still need some tweaks to query representation
      (#2995), Serge will confirm, and Daniel
      will look into that next week

  - need to start thinking about summer qserv
    hackathon week (Fabrice can come to USA
    once this summer)

- possible tasks for AndyS:
    - review how we use scons in Qserv (this is a small,
      short term task)
    - data loading (partitioner writing directly in
      MyISAM format, merging data from multiple
      partitioners for the same chunk)
    - qserv core - tightening APIs/dependencies


Daniel:
  - pushed code with new structure and build system

  - expecting to be back to lsst work next week


AndyH:
  - making some changes based on Daniel's feedback


Fabrice:
  - ongoing migration to eupsPkg: moved python,
    protobuf, mysqlpython
  - some issues found, need Mario to resolve them:
    a) mysqlpython depends on mysqlclient in stack,
       and on mysql in qserv, need to clean up this
       type of things
    b) also issue with packaging python (version used by Mario)
       different from what we used
    --> document the issues
  - expecting to finish migrating remaining dependencies
    next week
  - then planning to write how-to use eups
  - then will integrate with the latest qserv structure
    recently pushed by Daniel


AndyS:
  - started reading qserv docs
  - next week wants to understand development process,
    will talk to Daniel or Jacek


Bill (based on email exchange):
  -  will look into logging after midterm on Monday


Post mtg discussion:
- would be worthwhile checking performance of Aria vs MyISAM,
   looks like MariaDB distribution supports both Aria and MyISAM
