Support Change Feeds and Ingestion of Records with MetaData This change allows feeds to perform upserts and deletes in order to perform replication of an external data source. The change does so by performing the following: 1. The adapter produces [PK][Record]. (Record == null --> delete) 2. The insert is replaced by an upsert operator.
