 | `actRows`       | Number of rows output by the operator. |
-| `execution info`  | Execution information of the operator. `time` represents the total `wall time` from entering the operator to leaving the operator, including the total execution time of all sub-operators. If the operator is called many times by the parent operator (in loops), then the time refers to the accumulated time. `loops` is the number of times the current operator is called by the parent operator. `open` represents the time required for operator initialization. `close` represents the time from the operator processing all data to the operator ending. The time counted by `time` includes the time of `open` and `close`. When the operator is executed concurrently, the execution information will show the sum of all used `wall time`. At this time, `time`, `open` and `close` will be replaced with `total_time`, `total_open` and `total_close`. |

If the operator is called many times by the parent operator (in loops), then the time refers to the accumulated time. `loops` is the number of times the current operator is called by the parent operator. `open` represents the time spent initializing the operator. `close` refers to the time taken from when the operator finishes processing data to when it ends. The `time` value includes both `open` and `close` time. When the operator is executed concurrently, the execution information shows the sum of all used `wall time`. In this case, `time`, `open`, and `close` are replaced with `total_time`, `total_open`, and `total_close`. |
