> When data is inserted into existing tables and partitions, Catalog does not issue any metastore API calls. Metastore provides a API called {{fire_listener_event}} which can be used to add a {{INSERT_EVENT}} to the metastore notification log. This event can be used by other Impala instances to invalidate or update the filemetada information when data is inserted or overrwriten on a given table or partition.
