intermediateBulk Updates & Batch Processing
What's the difference between a bulk update and JDBC batching?
A bulk update executes ONE SQL statement affecting many rows, entirely skipping entity loading and dirty checking. JDBC batching still executes one statement PER entity, just groups several of them into fewer network round-trips (via hibernate.jdbc.batch_size) — it reduces round-trip count, not the total number of statements the database processes.
