Struct SqlParserRouter 

pub struct SqlParserRouter;

SQL parser-based query router that classifies SQL using a real AST.

Uses sqlparser-rs to parse the SQL into an AST, then inspects the statement type and structure to determine whether it should go to OLTP or OLAP. Falls back to keyword-based heuristic routing if parsing fails, and defaults to OLTP for unrecognised constructs (safety-first).

See the module-level documentation for the full routing table.
