TechFeddMastering Data Consistency Across Microservices
The article explores the challenges of maintaining data consistency in a microservices architecture, where each service operates independently with its own database. It highlights common issues like duplicate or lost data, network delays, and concurrency problems, and discusses strategies to address these challenges. The goal is to help developers build robust and scalable applications by understanding and mitigating data inconsistency in distributed systems.
Core Technical Concepts/Technologies Discussed
- Microservices Architecture: A design pattern where applications are built as a collection of small, independent services.
- Data Consistency: Ensuring that data remains accurate and synchronized across distributed systems.
- APIs (Application Programming Interfaces): Used for communication between microservices.
- Distributed Databases: Each microservice manages its own database, leading to potential consistency challenges.
- Concurrency Issues: Problems arising from simultaneous data access or updates.
- Network Delays: Latency in communication between services that can cause data inconsistencies.
Main Points
- Microservices Architecture:
- Applications are divided into small, independent services (e.g., order, payment, restaurant, delivery services).
- Each service operates independently, allowing for flexibility, scalability, and easier maintenance.
- Data Consistency Challenges:
- Duplicate or Lost Data: Occurs when updates fail or are not propagated correctly across services.
- Network Delays: Latency can cause services to operate on outdated data.
- Concurrency Issues:
Microservices architecture is a software design pattern where an application is built as a collection of small, independent services, each responsible for a specific function.
