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.
Enabled Feed Tests and Added External Library tests Feed tests had been switched off for a while due to having too many sporadic failures. Now, we are switching them back on. In addition, a new set of tests have been added to test that external library works as expected.
