TiKV cluster v5.0.1
How can I use pd-ctl or tikv-ctl to query the value of a key in the cluster and the number of keys in the cluster?
The content output by the print command is a bit difficult to understand.

Yes, this is a bit difficult to understand. Try using the region scan or scan command to get more readable results.

Does the approximate_keys in the region scan mean the number of keys in this region?

Yes, but it’s an estimated value.
