1. Minimal reproduce step (Required)
A use report that TiFlash has less rows than TiKV.
The root cause is that the range of some regions are in illegal format. For example:
table id: 283
start: 7480000000000001FF1B5F728000000000FF11BDC00000000000FA
end: 7480000000000001FF1B5F728000000000FF11BDC00000000000FB
We don't know how the data is ingested into TiFlash. But we need to make some checks on TiFlash side to prevent data lost.
