Spring Transaction Propagation: Deep Analysis of REQUIRED vs REQUIRES_NEW and Performance Trade-offs
This article provides an in-depth exploration of the core differences between PROPAGATION_REQUIRED and PROPAGATION_REQUIRES_NEW transaction propagation mechanisms in the Spring Framework. Through analysis of real-world multi-client concurrent scenarios, it details the key characteristics of both propagation types in terms of transaction independence, rollback behavior, and performance impact. The article explains how REQUIRES_NEW ensures complete transaction independence but may cause connection pool pressure, while REQUIRED maintains data consistency in shared transactions but requires attention to unexpected rollback risks. Finally, it offers selection advice based on actual performance metrics to avoid premature optimization pitfalls.
