The `auto_batch_dml` connection property enables automatic batching of DML statements, for example when using Hibernate. When this connection variable has been enabled, a JDBC connection will automatically buffer DML statements in memory, and send all buffered DML statements to Spanner as one batch when a query is executed or when the transaction is committed. This can significantly reduce the number of round-trips to Spanner, especially when using an ORM like Hibernate that generates many small single-row DML statements.
