JobWhen CDC is first enabled in the specified database and there is no transactional replication, two jobs are created for capture and cleanup:The capture job is used to scan the log files and write the change records to the change table. Called Sp_mscdc_capture_job, the scan parameters and scan intervals can be set based on the actual transaction throughput of the current library, resulting in a reasonable balance between performance overhead and tracking requirements.The cleanup job is to cle

There is a need in recent work that a more important business table is often inexplicably changed. In SQL Server, this kind of work cannot be done without capturing records beforehand. For capturing changes, the options you can consider include TRACE,CDC. However, the cost of trace is relatively large, it is not appropriate for a system with a higher load, and the CDC needs to affect the business library, s
