> Key: SPARK-36586
> URL: https://issues.apache.org/jira/browse/SPARK-36586
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.3.0
> Reporter: Wenchen Fan
> Priority: Major
>
> The ParsedStatement needs to be pattern matched in two analyzer rules and results to a lot of duplicated code.
> The new v2 command framework defines a few basic logical plan nodes such as UnresolvedTable, and we only need to resolve these basic nodes, and pattern match v2 commands only once in the rule `ResolveSessionCatalog` for v1 command fallback.
> We should migrate all the ParsedStatement to v2 command framework.
