[Subtask]: restrict memory usage. #16655

Open fengttt opened 1 month ago

Parent Issue

16617 Case 2 part 2.

Detail of Subtask

This is clearly a bug. Question will be,

  1. Do restrict really need to use that much memory. How much memory it is keeping. When it releases.
  2. Why restrict (later calling into table_scan, read,) does not reuse a vector from vector pool?

Describe implementation you've considered
