[TiDB Version] 5.4.3
Currently, there are 2 TiCDC nodes in the production environment. It has been observed that the sorter is particularly slow when the traffic is high. We want to scale out to see if this can solve the problem.

After scaling out the TiCDC cluster, will the TiCDC tasks automatically distribute to the newly added nodes?
