Recovery log analytics with a big data management platform
Provided are techniques for replicating relational transactional log data to a big data platform. Change records contained in change data tables are fetched. A relational change history with transaction snapshot consistency is rebuilt to generate consistent change records by joining the change data tables and a unit of work table based on a commit sequence identifier. The consistent change records are stored on the big data platform, and queries are answered on the big data platform using the consistent change records.
