try (Connection conn = DriverManager.getConnection(url)) {   conn.setAutoCommit(false);   int batchSize = 0;   int commitSize = 1000; // number of rows you want to commit per batch.    try (Statement stmt = conn.prepareStatement(upsert)) {     stmt.set ... while (there are records to upsert) {       stmt.executeUpdate();       batchSize++;       if (batchSize % commitSize == 0) {         conn.commit();       }    }  conn.commit(); // commit the last batch of records  }
