Redis is ubiquitous in Java development for caching, ranking, and distributed locks, but its transaction model differs from traditional databases; this article explains Redis transaction fundamentals, core commands (MULTI, EXEC, DISCARD, WATCH), common pitfalls, best practices, and interview FAQs to help developers avoid mistakes.
Redis, a non‑relational database, implements transaction-like behavior using commands such as MULTI, EXEC, DISCARD, and WATCH, allowing queued execution, optimistic locking, and various rollback granularities, though its semantics differ from traditional relational database transactions.
