[GitHub] [shardingsphere] RaigorJiang opened a new issue, #23854: Refactoring of QueryableRAL implementation
RaigorJiang opened a new issue, #23854:
URL: https://github.com/apache/shardingsphere/issues/23854
Related to #23772.
Some `queryable RAL` is also implemented through `DistSQLResultSet`, `GlobalRuleDistSQLResultSet`, now we need to adjust them to executor mode.
It should be noted that there are some differences between `queryable RAL` and `RQL`, and they are not all at the database level.
For example, `show compute nodes` needs to query `InstanceContext`, while `show dist variable` needs to query `props` in metadata.
Therefore, `QueryableRALExecutor` should be split into `DatabaseRequiredQueryableRALExecutor`, `InstanceContextRequiredQueryableRALExecutor` and `MetaDataRequiredQueryableRALExecutor`.

After this adjustment, the realization of `QueryableRALStatement`, `QueryableGlobalRuleRALStatement`, `QueryableScalingRALStatement`, etc. can also be unified.
