Permissions - clarifications

  • Summary:

    1. Can a schema manager edit schema name & description?
      • We have options to do this at both the schema page & db page.
      • Currently, the UI allows schema managers to do this at the schema page, but not at the DB page. We need to make this consistent.
      • The product spec does not provide clarification into names and descriptions. This is a DDL operation on the schema itself, and based on the spec it should only be allowed if the user has manager access on the DB. However, the backend allows this.
    2. If we allow editing, should we allow delete? The backend allows this, the frontend doesn’t. The spec says we shouldn’t allow this.
  • It’s okay if the schema manager can edit/delete the schema.

    • Requires a quick change on frontend work

We also discussed - conclusion was that the backend behavior/product spec makes sense but we need a better UX. We won’t worry about it for launch - users and permissions just needs to be working; not necessarily really smooth.

Demo server readiness

  • Summary: What steps do we need to take to make demo work during launch?
  • Participants: Dom, Brent, Kriti, Mukesh, Pavish, Sean (partial)


  • Performance is a problem:
    • Request timeouts due to reflection
    • bogging down on reflection
    • Multiple servers hooked up to same DB doesn’t help
  • Too many connections
    • Increase connection limit?
    • Optimize connection management in the code
    • Reduce timeout of Postgres sessions
      • Slow down demo server, but won’t crash it.
  • Figure out how to set up load balancer if we need it.
  • Note: ensure the ArXiv data loader doesn’t write to the template

Load tests



  • Getting the demo server 100% reliable before Monday is not a reasonable goal.
  • We shouldn’t be trying to identify all issues at once.
  • We need to rapidly iterate on fixes and load testing.


  1. Figure out setting up (sticky sessions) load balancer and additional servers in GCP - Mukesh
  2. Optimize Postgres settings - session timeout, connection limit, etc. - Dom
    • Connections may be memory intensive, pay attention to that.
    • Postgres connections according to docs, 128 MB
      • Not seeing that in production, 0.3% of 8 GB
      • 300 connections will use ALL the memory
  3. Optimize reflection in the Mathesar codebase - Dom
  4. Optimize connection management in the Mathesar codebase - Mukesh
  5. Load test more and find other problems - Dom
