Does `GetPlan` need to support:
- [ ] long window
- [ ] engine options cluster_optimized_?

The issue references a comment in issue #2626 about ddlparser and sql compile options. Need to examine the GetPlan function in the ddlparser component to see if it supports 'long window' and 'engine options cluster_optimized_?'. Start by locating the ddlparser source files and the GetPlan implementation. Check the linked issue for context. Determine what these options are and how they should be integrated. Testing likely involves SQL compilation tests.
