rdb-HistoryServiceArchiveProvider

This component supplements queries against local history records with archived history records that were previously exported to a remote (cloud) RDBMS using the standard drivers: rdbSqlServer, rdbMySQL, and rdbOracle. These archived history records are from an external data store, a relational database.
