Ability to persist/merge hashed target data into reconcilation DB #18
Description
Context / Goal
In #6 we implemented initial ability to persist the source data into the reconciliation DB. We now need to extend this to query the target database with its dataset definition, and augment the data with that from the target database.
Expected Outcome
- be able to load data from a target DB using its dataset query
- insert new rows where a row containing the
MigrationKeyis not found already - update rows with the hashed target data if the row already exists
Out of Scope
- generating a report of differences between the two datasets
