How is the load on the target database? Is it reaching the write bottleneck?

| username: maokl | Original post link

The load is within the normal range, with low CPU, IO, and memory usage. TPS is 1200+ and QPS is 4500+.

You can check the status of the upstream TiDB cluster and the write status of the downstream separately.
