Eventual Consistency allows systems to remain available while tolerating temporary data inconsistencies.
In microservices, Eventual Consistency means data changes propagate gradually through the system, rather than instantly. This is crucial for maintaining availability, especially during network partitions or service failures. For example, in an e-commerce platform, a product's inventory might not reflect a recent sale immediately across all services, but will eventually synchronize, ensuring the system continues to operate.
