Describe This Problem

In #1150, a support_pushdown method is added, and we need to ensure analytic table and remote engine table can pushdown specific columns, analytic table tests have been added, but not for remote engine tables.

Proposal

• Explain support remote table
• Add pushdown check for remote table

I'd like to give this issue a shot. Are there avenues where I can ask questions?
