When performing data synchronization between already running clusters, I want to first use the backup tool to synchronize offline data to the backup cluster, and then start a CDC task...

If I configure a CDC task between two clusters now, and the collection table structures between Cluster 1 and Cluster 2 are the same, how should I configure it appropriately...

[Bug]: I performed CDC operations between two standalone clusters of Milvus, but after creating the task, the background program reported an error: "fail to get the ts data".
