5 min

See if there are any updates on:

All
  • Studio for kdb+ : Try to get a conversation going between Rob and Charlie.
  • q Insight Pad : Oleg not interested in open-sourcing at this time.
15 min

Discuss Connection Manager contribution.

  • Details mailed out on data-tech-kdb list.
All
  • It's a draft specification at this time.
    • Code readily mined from internal MSKDB offering and custom implementation built by Business Metrics team.
    • Support for retry timer.
    • Requires changes at every hopen and IPC call since it issues its own handles for accounting purposes.
    • Intention to support ZooKeeper lookup for highly distributed plants and failover requirements.
    • Think about how you, as a developer, think the API would work in real code and toss around ideas on the data-tech-kdb list.
10 min

Smaller contribution ideas?

  • Last call, dashboard integration was one idea that sounded promising.
  • That said, someone at MS had a memory issue and found AquaQ's memusage.q contribution very helpful!
  • Aim for a broader cross section of users.
All
  • Check the Aaron Davies repository for any utilities / snippets that you'd like FINOS-ified:
  • MSKDB utility to ungroup tables with string columns should be a quick win.
5 minAOBAll
  • Recent Shakti meetup?
    • Has encryption.
    • Persistence is simpler?
      • One file per day with appending.
      • Seems like per-column schema migration of kdb+ wouldn't apply.
  • Any IDE-related utilities?
    • A couple of Emacs users, but no real Elisp utilities for kdb.
    • One IntelliJ IDEA user due to previous Java work.
      • Doesn't do 3-way diffs very well?
  • Better utilities for HTML generation?
