Meeting notices

• FINOS Project leads are responsible for observing the FINOS guidelines for running project meetings. Project maintainers can find additional resources in the FINOS Maintainers Cheatsheet.

• All participants in FINOS project meetings are subject to the LF Antitrust Policy, the FINOS Community Code of Conduct and all other FINOS policies.

• FINOS meetings involve participation by industry competitors, and it is the intention of FINOS and the Linux Foundation to conduct all of its activities in accordance with applicable antitrust and competition laws. It is therefore extremely important that attendees adhere to meeting agendas, and be aware of, and not participate in, any activities that are prohibited under applicable US state, federal or foreign antitrust and competition laws. Please contact legal@finos.org with any questions.

• FINOS project meetings may be recorded for use solely by the FINOS team for administration purposes. In very limited instances, and with explicit approval, recordings may be made more widely available.

    • Avoid focusing on search box when switching tabs.
  • Option to disable file watcher.
    • Studio can take long pauses for those with home directories on slow network drives.

• (10 min) Discuss whether qPython should support for serialization of verbs?

  • https://github.com/finos/qPython/blob/main/qpython/qwriter.py
  • Would allow where clauses to be constructed in parse tree format.
  • Not that much interest.
    • Concerns about such queries being blocked by a security shim like controlaccess.q
      • https://github.com/simongarland/dotz/blob/master/controlaccess.q
    • Offer predefined filters for where clauses instead.
    • Pass a string argument that gets parsed for super-flexible querying.
  • Future of qPython given PyKX release?
    • PyKX requires a KX Insights license.
    • Will take a while for PyKX to become widespread.
    • Takes a long time to migrate off legacy code, so qPython will be around a while.
