The key to integrating with ApacheKafka with Go is to select the right client library and properly configure producers and consumers. First of all, it is recommended to use the segmentio/kafka-go library. Because it is concise and conforms to the Go language habits, after installation through gogetgithub.com/segmentio/kafka-go, you can create Writer to send messages and set Addr, Topic and Balancer policies; then configure Reader to realize message consumption by specifying Brokers, Topic and GroupID, support consumer groups and manual partition allocation; be sure to use context to control timeouts, enable TLS/SASL to ensure security,

This article explores how to convert []int slices to []uint8 (byte array) in Go. Given that the size of the int type in Go is platform-related (32-bit or 64-bit), the article details how to use the reflect package to dynamically obtain the int size, and combine the encoding/binary package to convert efficiently and safely in a large-endian manner, providing specific code examples and precautions to help developers cope with cross-platform data conversion challenges.

Go's http.Client automatically tracks up to 10 redirects by default; 1. By default, redirects such as 301, 302, etc. will be automatically processed and the final response will be returned; 2. You can customize behavior by setting the CheckRedirect function, such as limiting the number of redirects, and return an error when len(via)>=3 to limit up to 2 redirects; 3. You can prevent redirects and get the original redirect response by returning http.ErrUseLastResponse, which is convenient for checking the Location header; 4. You can modify the request during the redirection process, such as deleting the Authorization header according to the target domain name to prevent sensitive information leakage; 5. You need to pay attention to looping

sync.Map should be used in concurrent scenarios with more reads and fewer reads and writes. 1. When multiple goroutines are read and write concurrently and explicit locks are needed; 2. Use Store, Load, Delete, LoadOrStore and Range methods to operate key-value pairs of type interface{}; 3. Pay attention to its lack of type safety, poor performance in write-intensive scenarios and requires type assertions; 4. In most cases, conventional mapping with sync.RWMutex is simpler and more efficient, so sync.Map is not a general alternative and is only suitable for specific high read and low write scenarios.
