Tea with Sam: Data Filtering in Oso using Partial Evaluation

Join Oso cofounder/CTO Sam Scott on Twitch for another behind-the-scenes look into Oso development and how we recently built data filtering – the ability to authorize a collection of objects — by making major upgrades to the virtual machine powering the Oso policy language.

Event Details

In Oso v0.11, we added support for data filtering by enabling the Oso policy language to pass around partially-evaluated terms as "constraints". In this session, Sam will cover:

  • Basics of the policy language
  • What we mean by "constraints"
  • Why we chose this solution
  • How the virtual machine handles constraints
  • The feature in action – filtering SQL datasets using Oso policies
  • Other use cases for constraints

Help us make the session about you too! Come with problems and questions, and let's have an open discussion. Anything and everything is welcome, your feedback helps us build a better product.
