Abstract: Systems, devices, and methods are provided for implementing shadow data lakes. In at least one embodiment, a deletion workflow obtains a deletion request from a delete request cache service, gets attestation details from an attestation service, submits a job to scan one or more records from a source table of a data lake and publish the one or more records to a deleted records table of a shadow data lake, and cause deletion of the one or more records from the data lake.
