 ## Does TiDB support `SELECT FOR UPDATE`?
 
 Yes. When using pessimistic locking (the default since TiDB v3.0) the `SELECT FOR UPDATE` execution behaves similar to MySQL.

-### How to scatter the hotspots?
-
-In TiDB, data is divided into Regions for management. Generally, the TiDB hotspot means the Read/Write hotspot in a Region. In TiDB, for the table whose primary key (PK) is not an integer or which has no PK, you can properly break Regions by configuring `SHARD_ROW_ID_BITS` to scatter the Region hotspots. For details, see the introduction of `SHARD_ROW_ID_BITS` in [`SHARD_ROW_ID_BITS`](/shard-row-id-bits.md).
