Ensuring Transaction Consistency in Multi‑threaded Spring Applications Using Programmatic Transactions

This article explains how to execute two dependent tasks in parallel with CompletableFuture, why the usual @Transactional annotation fails in a multi‑threaded environment, and provides a programmatic transaction solution that copies Spring's transaction resources between threads to guarantee atomic commit or rollback across all parallel operations.

Why @Transactional Can Trigger Production Outages: Lessons from a Long‑Transaction Failure

The author recounts a real‑world incident where a Spring @Transactional annotation caused database connection exhaustion, deadlocks, and a production outage, explains how long‑running transactions arise from holding a single connection during costly operations, and offers practical ways to avoid them by splitting methods or using programmatic transactions.
