v0.1.0

Bulk copy for SQLAlchemy + mssql-python — 10-50x faster writes via SQL Server's native TDS bulk load protocol.

API

• bulkcopy(conn, data, table_name, **kwargs) — direct function, no engine config needed, returns driver result dict
• register_bulkcopy(engine, **defaults) — SA do_executemany event hook with per-statement opt-in via execution_options(use_bulkcopy=True)
• bulkcopy_insert_method — pandas method= callable for df.to_sql()

Highlights

• All cursor.bulkcopy() kwargs pass through to the driver — future-proof when mssql-python adds new options
• on_complete callback for confirming bulkcopy was used and inspecting throughput
• Graceful fallback to executemany() with logging on any error
• Handles DataFrames, tuples, generators, lists-of-lists
• Column key → DB column name mapping via SA's compilation context
