This data might be provided as part of the query, loaded into the policy engine (asynchronously) before the query is sent, or fetched on-the-fly by the policy engine. Firstly, OPA would be running either as it's own service, as a sidecar in k8's, or in a Docker container. OPA can report provenance information at runtime. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. The request message body false.). are currently supported for the following APIs: OPA currently supports the following query performance metrics: The counter_server_query_cache_hit counter gives an indication about whether OPA creates a new Rego query evaluated with different inputs and external data. Open Policy Agent (OPA) was accepted to CNCF on March 29, 2018 and is at the Graduated project maturity level. This doesnt mean that OPA isnt a good choice for more traditional environments. OPA includes more than 150 built-in functions to help author policies, including support for JSON Web Tokens, networking, cryptography, time and much more. The path separator is used to access values inside object and array documents.
