Issue Information
| Issue Number | 701244a |
| Issue | In a Bush Join execution plan, when the left child node of a Hash Join is in a blocking state, the right child node, which is actually not blocking, is incorrectly identified as blocking. |
| Cause | The blocking information of the left child node was passed to the right child node, causing the right child nodeโs blocking status to be determined based on the left child nodeโs state instead of its own. |
| Solutions | Modified the system to prevent the blocking information of the left child node from being passed to the right child node, so the right child node determines its blocking status based solely on its own state. |
