Package-level declarations

BulkLoader is for the use case in which a destination first stages records in a temporary location, usually cloud object storage, then loads them into the destination database in bulk.

InsertLoader is for the use case where the destination connector builds an insert query (or specialized API call, a la BiqQuery) in one step, then executes the queries/requests in parallel in a second step. This is different from BulkLoader, which streams into object storage before bulk loading into a table.
