A Theoretical Study of DBLog: Certified Virtual Cuts for a Snapshot-Equivalent Replay of Live Databases
Announce Type: new Abstract: This paper is a theoretical follow-up to the 2019 DBLog paper, which introduced a change-data-capture (CDC) mechanism for both backfilling a downstream system from a live source database and streaming its ongoing changes, while the source keeps accepting writes.
