A mirror operation of the source system is performed to obtain CDC change operations. The method obtains a first CDC log as a first sequence of key-value pairs. A second snapshot of the source system is obtained and a set of key-value pairs is derived, which reflects the second snapshot. The first sequence of key-value pairs is compared with the set of key-value pairs to derive corrective CDC operations, captured as a set of key-value pairs. The corrective CDC operations represent corrections to be performed with respect to the first sequence of key-value pairs. A second CDC log is obtained as a second sequence of key-value pairs. The corrective CDC operations ensure that the second sequence of key-value pairs are coherent with the set of key-value pairs."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Tracking change data capture log history","description":"A method includes obtaining a first snapshot of a source system and deriving a set of key-value pairs reflecting the first snapshot.
