What difficulties can arise when using serialization within transactional processes?

The following difficulties may arise when using serialization in transactional processes:

• Data integrity issues: if serialization occurs in the middle of a transaction, the data may not be in a final state, leading to inconsistency.
• Loss of atomicity: serialization can violate the atomicity of a transaction if data is serialized before changes are committed.
• Performance issues: serializing large volumes of data within a transaction can slow down execution and increase lock times.
• Rollback difficulties: if a transaction is rolled back after serialization has occurred, additional logic may be required to restore the state.

For example, if an object is serialized before committing a transaction, and then the transaction is rolled back, the serialized data will be outdated.
