In existing logging libraries, including the slog logging library introduced in go 1.21.0, typically support log file rotation and segmentation. However, these functionalities are not built-in directly but require manual configuration to enable. This article was first published in the Medium MPP plan. If you are a

unsafe.Pointer In the previous article, we compared the differences between three types of pointers in Go. You can check that out before diving into this one. Now, let's summarize the distinctions between the three pointer types. * Ordinary pointers: They do not support pointer arithmetic, retain both address

What's Consistent Hashing First, let me quote a definition from Wikipedia: In computer science, consistent hashing is a special kind of hashing technique such that when a hash table is resized, only 𝑛/𝑚 keys need to be remapped on average where 𝑛 is the number of keys and 𝑚 is the
