研究方向
Consult the referenced issue pingcap/tidb#673 for historical context. Study TiDB's SQL parser and planner to understand how new function types and data types are added. Examine MySQL's spatial extensions for guidance. Since there is no detailed specification, propose a design document outlining the scope, implementation plan, and backward compatibility considerations. Seek maintainer feedback on the proposal before proceeding.
