What problem does two-phase commit (2PC) address in distributed transactions?

Problem Statement

Explanation

2PC coordinates multiple resource managers to vote on success, then either commits all or aborts all. It preserves atomicity across systems. It adds latency and failure modes like in-doubt transactions. Many modern designs prefer idempotent events with eventual consistency unless strict atomicity is required.
