Changed

Describe enhancements or major fixes.

Streamline checksum verification

This enhancement de-duplicates checksum verification in Archivematica, which helps to improve the performance of Archivematica in processing large transfers (many files and/or large files). This enhancement includes three changes:

• Remove the "Verify checksums generated on ingest" micro-service
• Enhance the "Verify AIP" micro-service to bulk query the database for transfer-generated checksums and then verify that they match what is documented in the bag-generated manifest-<ALGORITHM>.txt.
• Have "Verify AIP" create an AIP-level "fixity check" PREMIS:EVENT that it can pass to the Storage Service, which will document this verification in the pointer file.

This should not impact regular workflows, but it is worth noting that there is no AIP-level fixity check PREMIS event for uncompressed AIPs, which don't have pointer files. For uncompressed AIPs, there are still object-level fixity events in place. Note that there is an issue in the Archivematica Issues repository regarding this note - Problem: uncompressed AIPs need pointer files #32
