Trace Events from different queries can be distinguished by the query_id These sessions are open format for community members to ask questions. A base document conflict will occur if the parent portion of the path refers to a non-object document. OPA was built from the ground up to run in containerized, cloud native environments, and its lightweight nature allows it to be deployed in highly distributed environments, such as microservice architectures and serverless workloads. OPAs configuration and APIs must be secured according to the security guide. Trace Event objects contain the following fields: Queries often reference rules or contain comprehensions. Lastly, I would like to share my thought on using OPA to do the authorization. store, etc. Updating the SDKs will require re-deploying the service.
