- How does Golang technology handle data consistency in distributed systems?
- There are three main mechanisms for maintaining data consistency in distributed systems: Transactions: Guaranteed atomic operations that either all succeed or all fail. Lock: Control concurrent access to shared resources to prevent inconsistencies. Optimistic Concurrency Control (OCC): non-blocking, assuming that transactions will not conflict, rolling back modified transactions.

- Metrics for performance testing in Go language
- In Go language performance testing, common metrics are used, including: Throughput (TPS): measures the number of requests processed per unit time, reflecting the application's ability to handle concurrent requests. Response Time (RT): The time it takes from sending a request to receiving a response, a measure of user experience and application sensitivity. Concurrency (C): The number of requests processed simultaneously, reflecting the application's ability to handle parallel operations. Resource Consumption (M): System resources consumed by an application, helping to determine whether the application is utilizing resources efficiently. Error rate (E): The number of errors encountered when processing requests, a measure of the stability and reliability of the application.

- Golang API caching strategy and optimization
- The caching strategy in GolangAPI can improve performance and reduce server load. Commonly used strategies are: LRU, LFU, FIFO and TTL. Optimization techniques include selecting appropriate cache storage, hierarchical caching, invalidation management, and monitoring and tuning. In the practical case, the LRU cache is used to optimize the API for obtaining user information from the database. The data can be quickly retrieved from the cache. Otherwise, the cache can be updated after obtaining it from the database.

- How to reduce memory footprint in Golang API?
- In order to reduce the memory usage in GolangAPI, you can: Use a memory pool to avoid frequent allocation and release of memory. Use byte slices instead of strings to reduce byte storage. Release resources that are no longer in use, such as file handles and database connections. Use memory profiling tools to find memory leaks and high memory consumption.

- How does Golang technology support distributed tracing in distributed systems?
- Distributed tracing in Go is critical, allowing developers to trace the flow of requests through a distributed system for troubleshooting and performance optimization. The Go language provides the OpenTracing library, which is a platform-independent API that allows applications to interact with tracking systems (such as Zipkin, Jaeger, etc.). By using the OpenTracing library, developers can easily implement distributed tracing in Go applications, including creating traces, adding labels, simulating execution operations, and logging events. By sending tracing data to a centralized tracing system, users can visualize the flow of requests through the system and troubleshoot performance issues across services.

- What common performance pitfalls should be avoided with Golang APIs?
- Best practice to avoid GoAPI performance pitfalls: Use more granular locking mechanisms, such as read-write locks or mutex locks, to avoid the performance impact of global locks. Control channel usage to avoid deadlocks and resource leaks. Use buffered channels to improve performance and avoid blocking on unbuffered channels. Optimize serialization/deserialization of performance-sensitive data, or directly manipulate raw data. Make full use of Go's concurrency features and use goroutine and synchronization mechanisms to optimize API performance.

- What pitfalls should we pay attention to when designing distributed systems with Golang technology?
- Pitfalls in Go Language When Designing Distributed Systems Go is a popular language used for developing distributed systems. However, there are some pitfalls to be aware of when using Go, which can undermine the robustness, performance, and correctness of your system. This article will explore some common pitfalls and provide practical examples on how to avoid them. 1. Overuse of concurrency Go is a concurrency language that encourages developers to use goroutines to increase parallelism. However, excessive use of concurrency can lead to system instability because too many goroutines compete for resources and cause context switching overhead. Practical case: Excessive use of concurrency leads to service response delays and resource competition, which manifests as high CPU utilization and high garbage collection overhead.
