• Found some additional notes from last meeting.
  
  • Will update and have the vote at the September call.

"Studio for kdb+" updates.

• Features in the pipeline?
• Icon status?
• FYI: May be viable to incorporate Creative Commons-licensed materials into FINOS projects.
  • FINOS will look at it more closely when the need arises.

• Icon designer on vacation.
  • Some internal review / tweaking to take place.
  • Will be released shortly after that.

FINOS Open Developer Platform.

• Might as well go with minutes in it since it's the way forward.
• Can try to convert non-minutes Wiki content to Markdown with Pandoc.
• Curious about manual override of Attendee List in case:
  • banks block login to GitHub unless named on the CCLA
  • attendees lazy / paranoid about persistent login to GitHub

Introduction to TimeBase as potential FINOS project.

• ODP (i.e., Github Actions Powered) meeting minutes need to be set up by Maurizio Pillitu and James McLeod (Unlicensed).
• See this issue, https://wwwgithub.deltixlab.com/products/timebase/
• Learn about:
  • Language it's implemented in.
  • How it scales.
  • Code snippets for querying from C++ / Java.
  • Asof join example?
  • Feature engineering?  Z-scores, etc.
• Think about who we can refer as participants in that project.

• finos/open-developer-platform/issues/161 , which tracks that. 

MemVerge vs qclone.

• "AquaQuarantine: MemVerge and kdb+" video suggested use cases where MemVerge might be used in a kdb+ plant.
• Shared memory pages sounds like something qclone can do for free without exotic hardware.
• Tease apart the use cases and see if they're interesting enough to put out the qclone plugin and cooperatively develop wrapper functions to support agreed-upon use cases.
• For cases that qclone doesn't work, investigate alternatives such as:
  • https://github.com/trishume/telefork
  • https://github.com/HewlettPackard/criu-pmem

• Use cases that attendees found interesting:
  
  • Debugging complex memory state with high computation.
  • EOD save down.
  • Snapshot to a file or across a network.
  • Worker processes for heavy compute like feature engineering.
• qclone limitations:
  • Doesn't offer any resilience in the face of host crash.
• Questions:
  • Process management for clones?
  • Containerization?
• Will try to get qclone PoC released for experimentation.

• Discussion pivoted to Cloud.
  • Morgan Stanley and JPMC looking for ways to simplify deployment of kdb+ on the cloud.
  • Tools to manage the cooperating processes typical of a kdb+ plant?
  • FINOS Cloud Service Certification currently more about standards.
    • No actual code.
