- ๐๐ฒ๐๐ฒ๐ฟ ๐๐ฎ๐๐ฎ๐ฏ๐ฎ๐๐ฒ ๐ฅ๐ผ๐๐ป๐ฑ ๐ง๐ฟ๐ถ๐ฝ๐: Instead of sending one query at a time, batch processing groups multiple queries into a single round trip.
- ๐๐ป๐ต๐ฎ๐ป๐ฐ๐ฒ๐ฑ ๐ ๐ฒ๐บ๐ผ๐ฟ๐ ๐ ๐ฎ๐ป๐ฎ๐ด๐ฒ๐บ๐ฒ๐ป๐: Proper session handling prevents memory issues like
OutOfMemoryException. - ๐ ๐ฎ๐๐๐ถ๐๐ฒ ๐ฃ๐ฒ๐ฟ๐ณ๐ผ๐ฟ๐บ๐ฎ๐ป๐ฐ๐ฒ ๐๐ฎ๐ถ๐ป๐: Imagine reducing 2000 database calls to just 20 for 1000 inserts or updates!

1๏ธโฃ ๐ฆ๐ฒ๐ ๐๐ฎ๐๐ฐ๐ต ๐ฆ๐ถ๐๐ฒ: Configure hibernate.jdbc.batch_size. This controls how many records are processed in one batch.
2๏ธโฃ ๐๐น๐๐๐ต ๐ฎ๐ป๐ฑ ๐๐น๐ฒ๐ฎ๐ฟ ๐ฆ๐ฒ๐๐๐ถ๐ผ๐ป๐: Use session.flush() and session.clear() periodically to free up memory and avoid performance degradation.
3๏ธโฃ ๐ข๐ฝ๐๐ถ๐บ๐ถ๐๐ฒ ๐๐ป๐๐ฒ๐ฟ๐๐/๐จ๐ฝ๐ฑ๐ฎ๐๐ฒ๐: Enable hibernate.order_inserts and hibernate.order_updates to group similar operations together for efficient execution.

If you're using ID generation strategies, avoid the identity generator. Instead, opt for strategies like sequence or pooled. This can reduce your database round trips! ๐
