 * Type: int
 * Description: Used to limit the maximum number of scan keys that a scan node can split in a query request. When a conditional query request reaches the scan node, the scan node will try to split the conditions related to the key column in the query condition into multiple scan key ranges. After that, these scan key ranges will be assigned to multiple scanner threads for data scanning. A larger value usually means that more scanner threads can be used to increase the parallelism of the scanning operation. However, in high concurrency scenarios, too many threads may bring greater scheduling overhead and system load, and will slow down the query response speed. An empirical value is 50. This configuration can be configured separately at the session level. For details, please refer to the description of `max_scan_key_num` in [Variables](../../../advanced/variables).
   - When the concurrency cannot be improved in high concurrency scenarios, try to reduce this value and observe the impact.

 * 类型：int
 * 描述：用于限制一个查询请求中，scan node 节点能拆分的最大 scan key 的个数。当一个带有条件的查询请求到达 scan node 节点时，scan node 会尝试将查询条件中 key 列相关的条件拆分成多个 scan key range。之后这些 scan key range 会被分配给多个 scanner 线程进行数据扫描。较大的数值通常意味着可以使用更多的 scanner 线程来提升扫描操作的并行度。但在高并发场景下，过多的线程可能会带来更大的调度开销和系统负载，反而会降低查询响应速度。一个经验数值为 50。该配置可以单独进行会话级别的配置，具体可参阅 [变量](../../advanced/variables.md) 中 `max_scan_key_num` 的说明。
