RaigorJiang opened a new issue #13702: URL: https://github.com/apache/shardingsphere/issues/13702
Hi community, We have collected some user requirements. >We hope that when using Proxy, we can execute DDL on the physical database (for example, add a column to a table), and then refresh the metadata in the Proxy, so that ShardingSphere can recognize the newly added column. Such as this issue: - https://github.com/apache/shardingsphere/issues/11755 \ Now, I plan to add a syntax for refreshing table metadata in DistSQL, so that users can control when to trigger the refresh. The syntax is as follows: 1. Refresh metadata of all tables: ```sql refresh table metadata; ``` 2. Refresh metadata of the specified table: ```sql # from a random resource refresh table metadata t_order; # From the specified resource refresh table metadata t_order from resource ds_0; ``` At the same time, `ContextManager` needs to add a new API to really refresh the metadata. @menghaoranss can you help design the ContextManager interface? -- This is an automated message from the Apache Git Service.
