What Is Transaction Management?

Transaction management is the coordination of a transaction's lifecycle — starting it, committing it when the work succeeds, and rolling it back when something fails — so that a unit of work either completes in full or has no effect at all. It is how an application or framework enforces the ACID guarantees of a transaction in practice.

The Transaction Lifecycle

Every managed transaction moves through the same three stages:

  • Begin. A transaction is opened, marking the start of a unit of work. Everything from this point on is provisional.
  • Commit. Once every operation has succeeded, the transaction is committed and its changes become permanent and visible to others.
  • Roll back. If any operation fails, the transaction is rolled back, discarding every change so the data returns to its prior state.

Getting these boundaries right — where a transaction begins and ends, and what happens on failure — is the heart of transaction management.

Programmatic vs Declarative

There are two ways to control those boundaries:

  • Programmatic. You call begin, commit, and rollback explicitly in your code. This gives fine-grained control but mixes transaction handling into your business logic.
  • Declarative. You mark a method as transactional — for example with Spring's @Transactional annotation — and the framework opens, commits, and rolls back the transaction around it for you. This keeps the boundaries out of your business logic and is the common choice in modern Java applications.

Transaction Managers

A transaction manager is the component that actually drives commit and rollback and connects the application to the underlying resource. In Spring, a PlatformTransactionManager handles this for a single resource; for work that spans several systems, a JTA transaction manager coordinates a distributed transaction using two-phase commit. A transaction manager also handles concerns such as propagation — whether a method joins an existing transaction or starts a new one — and the isolation level applied to the work.

Transaction Management with Valkey and Redis

Redisson, the Valkey and Redis Java client, provides transaction management at every level. Its RTransaction API supports the programmatic style with explicit commit() and rollback(), while RedissonTransactionManager plugs into Spring so you can manage Valkey and Redis transactions declaratively with @Transactional, exactly as you would a relational database. For work that spans Valkey or Redis and another resource, the RXAResource implementation lets Redisson take part in JTA-managed distributed transactions through XA. Transaction management features are part of Redisson PRO.
