Eventual Consistency Models
Microservices can use eventual consistency models, where updates are propagated asynchronously and conflicts are resolved over time. This allows each microservice to maintain its own copy of the data and eventually converge to a consistent state.
What is eventual consistency between Microservices?
Eventual Consistency between microservices refers to the concept that, in a distributed system where data is replicated across multiple microservices or databases, eventual consistency is maintained over time. This means that while updates to data may not be immediately reflected across all microservices, they will eventually converge to a consistent state.
- In a microservices architecture, each microservice manages its own data store, and data may be replicated or cached across multiple microservices for performance and scalability reasons.
- However, ensuring that all copies of the data remain consistent can be challenging due to the distributed nature of the system and the potential for network delays, failures, or conflicts.
To achieve eventual consistency between microservices, various strategies, and techniques can be used, such as:
