Polar, a Declarative Policy Language

oso engineer Alex Plotnick led a talk on Polar, oso's declarative policy language. Watch the 30-minute recording below to hear from Alex on:

  • An introduction to oso
  • Writing authorization policies with Polar, starting from "deny everything" and building up to model-specific "allow" rules
  • How the Polar VM uses an event-driven FFI interface to collect data during query execution from application languages like Python, Node.js, etc.
  • How Polar can collect authorization constraints from a policy and translate them into an ORM filter to efficiently retrieve a collection of authorized resources.
