Brief description of project, scope and aimed deliverables

Currently only full datasets can be uploaded or downloaded. Since only small amounts of donors/cbu actually change or get added/deleted, this is a wasteful exercise, both in capacity for validation, data transfer, and time. The differentials project aims to set up a method to allow for only partial data-uploads that contain only the differentials between the old and the new dataset.

Please note that Differential data-exchange means sending or receiving only the records that have been added, deleted or changed. This in contrary with the term Differences where is meant the (visual) indication if a record has been changed.

Scope includes both UPLOAD (GCD2 ingress) as DOWNLOAD/EXPORT of datasets (GCD2 egress)

1st stage:  provide the Differential upload by uploading a Differential File. The whole process is similar to current FULL upload.

2nd stage: An API real time differentials  update may be implemented.

Deliverables are

  • Description and pro's and cons for various methods that allows for differential UPLOADS.
  • Technical design of possible solution
  • Implemented solution.
