As shown in the figure below, by using the command show table video_v2 regions to check the regions, it is found that there is a “gap” in the middle. The ID of the table video_v2 is 1084. What is the situation with this phenomenon?

It’s not a gap.
That’s start_key=prefix+“”
The previous region’s end_key=prefix+“”

If you merge all the start keys and end keys together, you will eventually get a start_key=prefix+“” end_key=prefix+“”
