Selgitage RAF-mustri tööpõhimõtet ja selle rakendamist programmeerimises

The RAF (Read-Allocate-Flush) pattern is an approach to memory or cache management that involves three steps:

1. Read — obtaining data from the source.
2. Allocate — reserving resources or memory for storing data.
3. Flush — writing or clearing data, such as writing to disk or clearing the cache.

In programming, this pattern helps manage resources efficiently, minimize delays, and prevent memory leaks.

An example in Go might look like this:

func processData() {
    data := readData()          // Read
    buffer := allocateBuffer()  // Allocate
    defer flushBuffer(buffer)   // Flush when exiting the function
    // Work with data
}

This approach ensures that resources are allocated and properly released after use.
