You are tasked with developing a Spring Boot application using Spring Data JPA, where ensuring the consistency of the data is crucial. How would you manage the transactions in the application to ensure the integrity and consistency of the data?
- Disable transactions altogether to improve application performance, relying on the database's ACID properties to maintain data consistency.
- Implement programmatic transaction management by manually starting and committing transactions in each service method.
- Use declarative transaction management with the @Transactional annotation and ensure that each service method operates within a transaction boundary.
- Use distributed transactions with multiple databases to enhance data consistency across different data sources.
To ensure data consistency in a Spring Boot application using Spring Data JPA, it's best to use declarative transaction management with the @Transactional annotation. This allows you to specify transaction boundaries at the method level, ensuring that each service method operates within a transaction. Implementing programmatic transaction management or disabling transactions can lead to data inconsistency issues. Distributed transactions are complex and typically used in multi-database scenarios.
