| Description |
|
If we are evaluating an expression such as "$a.b", a query plan using the column index can avoid the two-step process of creating the partial document for "a.b" and then evaluating "$a.b" with it. Instead, we can evaluate the "$a.b" expression using the array info and values directly. |
