Description

Tagsync may receive a large number of ENTITY_UPDATE events when used in a large EDW environment. If an update entity is not associated with any tags (aka traits, classifications), then this event does not have material impact on the resource->tag associations in the Ranger, and therefore, can be safely dropped. Processing such event adds processing overhead to tagsync, ranger-admin and network, and also causes ranger-admin database to be populated with service-resource that is not tagged and is not needed for access evaluation.
