Zusammenfassung:A method for backfilling records dropped by a distributed node system during a transfer to an external database includes initially determining whether an attempt to transfer a data record failed or succeeded. In response to determining that the transfer succeeded, the data record is appended at its original location include a first transfer status identifier. In response to determining that the transfer failed, the data record is appended to include a second transfer status identifier and queued copy of the data record is created by copying the data record to a delayed re-try queue. The method further includes verifying that the transfer status identifier of the queued copy is identical to the transfer status identifier of a newest version of the data record within the distributed node system and, responsive to the verification, attempting a subsequent transfer of the queued copy of the data record to the external database.
