+#### Tablet-Specific Targeting
+
+For debugging and troubleshooting, you can route queries to a specific tablet by its alias:
+
+```sql
+USE `keyspace:shard@tablet_type|tablet-alias`
+```
+
+For example:
+```sql
+USE `mykeyspace:-80@replica|zone1-0000000100`
+```
+
+This targets a specific tablet within a shard, providing stable routing when you don't have direct access to the underlying MySQL instance. The tablet alias uses the format `cell-uid` (e.g., `zone1-0000000100`).
+
+Keep in mind:
+- You must specify both the shard and tablet type (before the `|`) when targeting a tablet.
+- Once set, all queries in the session route to this tablet until you change or clear the target.
+
+This is useful for:
+- Debugging queries on a specific tablet
+- Testing replica consistency by targeting individual replicas
+- Ensuring query stability during troubleshooting
+
