Fork Studio for kdb+.

• Charlie changed the license to Apache 2!

  • https://github.com/CharlesSkelton/studio

• Next steps?

  • Seems like it could be a separate project.

  • Owners?  Ci / CD integration?

All

• No one from FINOS on the call to discuss Studio for kdb+.

  • Revisit this next time.

• Someone contacted maintainer of q Insight Pad about open sourcing it.

  • Current thinking is that open source is a possibility, but not something as permissive as an MIT license.

  • Would still like to retain a measure of control over its direction and who might support it commercially.

JupyterQ / PyQ notebooks?

• Any interest in contributions for those?

• Since q doesn't have a proper "spawn" call, it's arguably safer to do HDB maintenance (copy / link / remove files) from Python.

• More robust examples of q / Python interop?

  • JupyterQ / embedPy examples of saving DataFrames to Pickle?

  • PyQ examples of loading serialized q into Python?

All

• The idea of using Python scripts for HDB maintenance was not popular.

• The preferred direction was:

  1. Use q builtins as extensively as possible (hdel, etc.)

  2. Lobby for a proper function that takes an argument vector.  (Possibly as a -n!x "internal" function.)

  3. Release a plugin that wraps fork(2) / execvpe(3).

• Best if members lobby Kx for #2 so that the entire community can benefit.

New ideas to increase contributions?

• Snippets gallery instead of fully-baked libraries?

• Just let Peter go all out? 

All

• Might be nice to get an example of kdb integration with Perspective, a JPMC contribution to FINOS:

  • https://perspective.finos.org/

• TorQ has a Grafana adapter

  • https://www.aquaq.co.uk/q/ask-shall-receive-grafana-kdb-adaptor/

  • https://github.com/grafana/grafana

  • Jonny will look into what might be involved with contributing that.

• Module loader is still highly desirable.

  • Support for search paths would be required given the way silos form in enterprises.
