   ### Description
   
   Hi Team! I have a requirement where i need to execute update command on a 
table with a `Duplicate model` . 
   
   In my case, I can't use `Unique model` because it will affect prefix index 
hits
   
   Anyone who can provide some light on the same , a resolution would be highly 
appreciated
   
   Thank you all in advance

   The `ClickHouse` provides  a heavy operation not designed for frequent use.
   
   like this:
   ```sql
   ALTER TABLE [db.]table [ON CLUSTER cluster] UPDATE column1 = expr1 [, ...] 
[IN PARTITION partition_id] WHERE filter_expr
   ```
