How Cerbos works with ChromaDB
When users should only see a subset of data, traditional approaches filter results in application code, leading to duplicated logic, inconsistencies, and performance problems at scale.
Cerbos query plan evaluation converts your authorization policies into native ChromaDB filters. Instead of fetching all data and filtering after the fact, your database only returns rows the user is authorized to see.
The same YAML policies that control API-level access now drive data-level filtering, one source of truth for who can see what, managed by product and security teams without touching application code.
How Cerbos filters data in ChromaDB
- Define authorization policies in YAML, Write resource policies that describe who can see which records, using roles and attributes.
- Request a query plan from Cerbos, Your application calls the PlanResources API, and Cerbos returns an abstract query plan.
- Convert the plan to a native ChromaDB filter, Map the Cerbos query plan to a ChromaDB query predicate so filtering happens at the data layer.
- Database returns only authorized rows, The query executes with the authorization filter baked in, no post-fetch filtering required.
FAQ
How does Cerbos filter data in ChromaDB?
Cerbos evaluates your authorization policies and produces a query plan. The ChromaDB adapter converts that plan into a native query filter, so your database only returns rows the user is authorized to see.
Does this replace application-level authorization checks?
Data filtering complements API-level checks. Cerbos handles both, the same policies that control who can access an endpoint also determine which rows are visible at the data layer.
