Attendees: Bill, Daniel, Fabrice, AndyH, AndyS, Serge, Jacek


Bill
  - installed log4cxx, integrated w/qserv in private environment
    to validate the prototype, can write log messages
  - wrestling w/scons, but on an older branch (not the latest
    reorg Daniel did)
    --> switch to the latest
  - Qserv now uses std streams, need to switch to the
    new style logging
  - prefix in the log messages: make configurable: eg,
    we want to turn it off for simple standalone tests


Daniel
  - documentation and cleanup for the latest reorg done
  - started working on join syntax for RefMatch:
    adding support for real join syntax, (it was comma-separated
    table list only so far). This will help with supporting
    near neighbor properly
     - might have something working today/tomorrow, but
       it will require more time "to get it right"
  - next: Serge needs to revisit what was blocking him
    last time he looked into RefMatch
  - still need to write a plug-in for query manipulation
  - need to discuss/design join support
     - Daniel will write a page first


Serge
  - still stuck with Ursa related work


Fabrice
  - at big data computing course most of last week
  - useful interactions with Mario, finishing packaging
  - best time to visit slac (Qserv Design/Hackathon week)
    end of Apr - beginning of May (4/28-5/3)


AndyS
  - started looking at the code


Jacek
  - #3087 (CSS)
    - implemented code for connecting Qserv with Zookeeper
    - working on integrating this with scons
    - full integration with Qserv next
    - need help with packaging, emailed Fabrice already
  - playing with MariaDb's Aria and MyISAM


Jacek
