In microservices, each service has its own database. Two-phase commit (2PC) across services hurts availability and performance \u2014 the Saga pattern is the standard alternative.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Saga?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A saga is a sequence of local transactions. Each step commits independently. If a step fails, compensating transactions undo previous steps in reverse order. Example: CreateOrder \u2192 ReserveInventory \u2192 ChargePayment. If payment fails, release inventory and cancel order.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Choreography vs Orchestration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Choreography:<\/strong> services react to each other&#8217;s events with no central coordinator. Simple for 2\u20133 steps; hard to debug at scale.<br><strong>Orchestration:<\/strong> a Saga Orchestrator service sends commands and tracks state. Better visibility and error handling for complex flows.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Kafka-Based Choreography Example<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Order Service publishes <code>OrderCreated<\/code><\/li>\n<li>Inventory Service consumes, reserves stock, publishes <code>InventoryReserved<\/code> or <code>InventoryFailed<\/code><\/li>\n<li>Payment Service consumes, charges card, publishes <code>PaymentCompleted<\/code> or <code>PaymentFailed<\/code><\/li>\n<li>On failure, compensating events trigger rollbacks<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Design Rules<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Every forward action needs a compensating action.<\/li>\n<li>Compensations must be idempotent.<\/li>\n<li>Store saga state (pending, completed, failed) for recovery.<\/li>\n<li>Use timeouts and dead-letter queues for stuck sagas.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Related: <a href=\"\/microservices\/outbox-pattern-reliable-event-publishing\/\">Outbox Pattern<\/a> \u00b7 <a href=\"\/microservices\/cqrs-pattern-microservices-kafka-2026\/\">CQRS with Kafka<\/a><\/p>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Want live microservices classes?<\/strong> <a href=\"https:\/\/www.alkademy.com\/courses\/microservices-architecture-intermediate-design-communication-resilience\">Join Alkademy<\/a> for instructor-led microservices architecture courses with hands-on projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Go deeper with the book:<\/strong> <a href=\"https:\/\/www.kindsonthegenius.com\/product\/practical-microservices-design-using-cqrs-and-event-sourcing\/\">Practical Microservices Design Using CQRS and Event Sourcing<\/a> by Kindson Munonye.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>Kindson Munonye is a software engineer and technical author specializing in microservices, CQRS, event sourcing, and distributed systems.
