The Clear Recorder Node (RN) Query History feature introduces CLI and GUI support on the DMF Controller for managing query records. Previously, deleting query history required direct interaction with the Floodlight (FL) API. This update allows for the removal of all query history entries through standard management interfaces. Note: The CLI and GUI support the deletion of the entire query history only; selective filtering of entries for deletion is not supported.

The Recorder Node (RN) supports being managed by CloudVision (CV) on-prem starting DMF 8.7.0. This feature extends support to CVaaS starting DMF 8.8.0. Recorder Node was not supported with CVaaS before 8.8.0 because of an RN requirement to store the query results file in CV while archiving the query results. However, this was not permitted on CVaaS as these files might contain data that cannot be stored in a cloud service. This feature supports CVaaS by allowing the RN to store query result files.
