If the coordinator node is unable to identify the correct node, it broadcasts the query to all nodes, and then coalesces the responses it receives from them.
如果协调者节点不能识别正确的节点，那么它会将查询广播给所有节点，然后聚集它从这些节点那里收到的响应。
Then, the node from which the query originates (the coordinator node) coordinates with the other partition nodes to find all qualifying rows.
然后，发出查询的节点（协调节点）与其他分区节点相协调以找到所有合适的记录行。
