+- In the disaggregated storage and compute architecture, specifies the TiFlash Write Nodes that TiFlash Compute Nodes do not send requests to.
+- The value is a string consisting of `store_id`s separated by `,`. For example, setting it to `"140,141"` means that TiFlash Compute Nodes will not send requests to TiFlash Write Nodes with `store_id` `140` or `141`. You can use [pd-ctl](/pd-control.md#query-tiflash-nodes-in-the-disaggregated-storage-and-compute-architecture) to query the `store_id` of TiFlash Write Nodes in the cluster.
