Expected behavior

Additional context

[critical27]

What's wrong with the result?
51 + 1 + 30 = 82 (count by tag)
81 + 152 = 233 (count by edge)

The actual vertex is not included in show stats

[foesa-yang]

I insert a vertex without a tag, why can't I find it with show stats?

[panda-sheep]

This has something to do with recent changes

When supporting the insertion of vertex without tag, the stats job needs to be compatible

[critical27]

show stats only scan tag/edge ("Space" | "vertices" is tag sum), we could handle the actual vertex in stats job later
