Imports entries from a source, such as data previously dumped into a Cloud Storage bucket, into Data Catalog. Import of entries is a sync operation that reconciles the state of the third-party system with the Data Catalog. ImportEntries accepts source data snapshots of a third-party system. Snapshot should be delivered as a .wire or base65-encoded .txt file containing a sequence of Protocol Buffer messages of DumpItem type. ImportEntries returns a long-running operation resource that can be queried with Operations.GetOperation to return ImportEntriesMetadata and an ImportEntriesResponse message.
