Manage database transactions in NestJS by using a transactional decorator to wrap service methods, automatically handling isolation levels and commit/rollback behavior. This ensures database calls are safely wrapped within a transaction context.

AsyncLocalStorage handles transaction boundaries by maintaining the transaction context across asynchronous operations. Combined with a Nest interceptor, it ensures TypeORM database calls execute within the correct isolated transaction scope.

Yes, you can control isolation levels for TypeORM transactions by passing transactional metadata through a custom decorator. This allows precise configuration of transaction boundaries and commit/rollback behavior in NestJS.

Yes, you need RxJS along with TypeORM and NestJS to implement transaction boundaries. RxJS is required to handle the transactional operations and manage the asynchronous commit/rollback control effectively.

The best way to handle complex transactions across multiple data sources is using a transaction runner to manage custom boundaries. This reduces the risk of data corruption and improves application reliability during complex transactional logic.

TypeORM transaction boundaries fail to rollback correctly when database calls are not properly wrapped within the transaction context. Using a Nest interceptor and transactional decorator ensures proper commit/rollback control and auditing.
