Read-Write Separated Connection Pool

Initialization automatically creates dedicated read and write connections. The write side is restricted to a single connection with WAL mode and immediate transaction locks, preventing write conflicts at the root. The read side exposes a configurable connection pool, maintaining stable query throughput under high concurrency. A background goroutine periodically performs WAL checkpoints to prevent unbounded database file growth.

Chainable Query Builder

All query operations are chained through the Builder pattern, supporting Where, OrWhere, Having, Join, GroupBy, OrderBy, Limit, Offset and other complete SQL clauses. All column and table names undergo regex validation and SQL reserved word checks. Parameters are always bound via prepared statements, blocking SQL injection at the syntax level.

Automatic Struct Binding

Query results can be mapped directly to Go structs or slices via the Bind() method, using db tags for column name matching. Passing a struct pointer automatically appends LIMIT 1, while passing a slice pointer scans all result rows. Developers no longer need to manually handle rows.Scan and column mapping logic.
