Conflict Resolution

Microservices can implement conflict resolution mechanisms to resolve conflicts that arise when multiple microservices update the same data concurrently. This can involve using timestamps, version numbers, or other techniques to determine the most recent update.

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:

4. Compensating Transactions

Microservices can use compensating transactions to undo or reverse the effects of a previous transaction if it is found to be in conflict with another transaction. This can help maintain consistency in the presence of conflicting updates....
