Discrete: Discrete collision Detection (default), collision detection with many other colliding bodies in the scene.
simply:1 The query optimizer uses the cost estimation model to calculate the cost of each plan, choosing the least expensive2 single-table scan, you need to calculate the cost, so the single-table index scan also need to calculate the cost3 The calculation formula for a single table is usually: cost = tuple number *io average4 Therefore, regardless of the scanning method, you need to calculate the number of tuples5 When an expression such as "A In (10, 20, 30)" is encountered, it is found that
