Incremental Run Stream

Ordering the query from the Runs endpoint by -finished_at, i.e. descending Run Finished Datetime, yields:

The incremental sync has been set up so that it works on replication_key = "finished_at", when an INCREMENTAL sync is run:

• If the bookmark is set, the stream is queried in reverse finished_at order.
• If the finished_at value is not set, the run is assumed to still be running so the record is included, plus the sort order implies that there should be records with populated finished_at appearing later in the stream - Repeated sync operation will yield the same records if the dbt Job Run is still underway, however this adheres to the 'at least once' delivery promise - https://sdk.meltano.com/en/latest/implementation/at_least_once.html
• Once the sync operation reaches records with populated finished_at, the values are compared with the bookmark and once the finished_at value becomes less than the bookmark the stream finishes syncing.
