[GitHub] [shardingsphere] sandynz opened a new issue #14719: Show error message when altering sharding configuration if scaling is not enabled

sandynz opened a new issue #14719:
URL: https://github.com/apache/shardingsphere/issues/14719


   ## Feature Request
   Currently, if scaling is not enabled, alter sharding configuration will take effect immediately, e.g. `ALTER SHARDING ALGORITHM`, `ALTER SHARDING TABLE RULE`. Though sharding configuration is altered immediately, but the underlying data is not scaled, in fact it cause issue. So we'll improve it.
   
   ### Is your feature request related to a problem?
   Yes
   
   ### Describe the feature you would like.
   If scaling is not enabled, show error message to user when altering sharding configuration.
