Creating multiple changefeeds where each one contains only one table results in all table tasks being sent to a single capture. This is unreasonable. I think before we bind a table to a capture, we should add more judgment conditions, such as considering the current tasks already bound to it. Then, we can choose the best capture to bind the table to, which will be better for this scenario. https://github.com/pingcap/tiflow/blob/master/cdc/scheduler/internal/v3/scheduler/scheduler_basic.go#L81-L82
What did you expect to see?
The tasks evenly distirbuted on different ticdc nodes.
What did you see instead?
All of them are bound on specific node.
Versions of the cluster
TiCDC version (execute cdc version):

#11331 seems just fixed the uneven distribute scenario for one changefeed muti-tables. This scenario is more like multiple changefeeds with one table task.
