Nosy Neighbour
The nosy neighbor anti-pattern occurs when a component or module within a system excessively monitors or interferes with the operations of other components, leading to unnecessary dependencies and performance degradation. This can result in increased coupling between modules, decreased modularity, and reduced system scalability.
For Example:
Consider a microservices architecture where one service constantly polls another service’s database for updates instead of subscribing to events or using asynchronous communication. This approach creates unnecessary load on the database and introduces tight coupling between the services, making it challenging to scale them independently.
Prevention Strategy:
- Event-Driven Architecture: Implement an event-driven architecture where services communicate through events rather than direct queries. This reduces the need for constant polling and minimizes unnecessary dependencies.
- Message Queues: Utilize message queues or publish-subscribe systems to decouple components and enable asynchronous communication. This allows services to communicate in a loosely coupled manner, improving scalability and performance.
What are Performance Anti-Patterns in System Design
While designing systems, it’s important to ensure they run smoothly and quickly. But sometimes, even though we try to make things efficient, we make mistakes that slow things down. This article talks about these mistakes how they can mess up a system and what measures we can take to prevent and fix them from happening.
