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



Round table status
==================

Jacek
  - xldb-healthcare fires
  - DMLT meeting
  - prepared outstanding (big) tickets for merging


AndyH
  - looking at HDFS


AndyS
  - put together working recipe how to setup dev env, see DM-228
  - debugging qserv build system
    - issues found, see DM-546
      - problem related to bug in SCons.Scanner
      - workaround: re-implement scanner?
       - not worth doing just for Qserv, but perhaps
         might be worth doing for lsst dm?


Bill
  - finalizing logging (exposed state, removed diagnostics context)
  - looking at packaging logging
  - first feedback from RHL (Seattle information discussions)
     - would be nice to reconfigure logging interactively
       - Bill thinks it is not hard
     - would be nice to have more debug levels
       - but incompatible with standard python logging
     - rhl will check logging docs and code and will get back
       to us with full comments shortly
  - next task after logging?
     - integrating with new xrootd client, or rearchitecting dependencies
        - former better defined, so better


Daniel
  - joined syntax: code tested, reviewed. Found & fixed
    (non trivial) problems when running final tests
    - Serge reviewing
  - xrd client next


Fabrice
  - improved init.d, in good shape, close to being
    fully Linux-standard compliant
  - tweaks to packaging zoo/kazoo/db
  - need input about client/css structure, see DM-58
     1) client
       - current client = an admin client, it depend on kazoo
       - long term, want client for users with no dependency
         on kazoo
       --> move current client to admin
       - do at dev week, after CSS code pushed to master
     2) watcher
       - it is for managing qserv node
         --> rename to "caretaker"
       - we need a place (new module) for that
         --> discuss at dev week


Serge
  - mostly non-lsst work
  - need to talk w/Daniel, next week. Topics:
    - separate plugin vs extending existing table plugin
    - how smart should we be about recognizing refmatch join



Merging for qserv release
=========================
  1) Serge: review latest patch
  2) Daniel: push code
  3) Jacek: push code
  * Fabrice code is independent, any time


FYIs
=====
  - we need to start using sprints for real
  - we should play with / start using hipchat

  - both sprints and hipchat will be discussed
    in more details next week at dev week


Goals for the dev meeting we have all next week
================================================
1) Qserv software that can be downloaded, built, installed,
configured, started and tested by a non-Qserv-expert, with
accompanying instructions. It is OK if some things are hacked,
not finished, not fully working and not in ideal state.

2) A plan for May-Aug (in a form of defined sprints) that
will get us to Qserv software that can be downloaded, built,
installed, configured, started and tested by a non-Qserv-expert,
with accompanying instructions WITHOUT hacks.

Question:
  - is "easy configure/load data" part of the S14 deliverable?
  --> discuss next week


Jacek
