Nessie currently supports 3 security modes:

  • No Security
  • Open Id Connect
  • AWS IAM Roles (limited to API calls, UI not supported)


Nessie authorization can only be done externally at the moment. However, because of the way that the REST APIs are defined, many operations can be controlled via a layer 7 firewall so that users and systems can be controlled depending on what read/write and types of operations should be allowed. This works especially well with Nessie run as an AWS Lambda using API gateway policies.

Metadata authorization

Nessie supports authorization on metadata. Details are described in the Metadata Authorization section.
