How to Efficiently Chunk a Slice in Go?

Slice Chunking in Go

As you have encountered, chunking a slice in Go can be achieved through the following steps:

1. Determine the Chunk Size: Calculate the desired chunk size by dividing the length of the original slice by the number of CPUs you want to use.
2. Iterate Over the Slice: Use a for loop to iterate over the original slice, starting from index 0.
3. Create a New Slice: For each chunk, create a new slice to store the chunked elements.
4. Append Chunks: Append the chunked elements to the new slice.
5. Append to Divided Slice: Append the newly created slice to the divided slice, which will hold the final chunked slices.

Here's an updated example based on your code:

var divided [][]string

numCPU := runtime.NumCPU()
chunkSize := (len(logs) + numCPU - 1) / numCPU

for i := 0; i < len(logs); i += chunkSize {
    end := i + chunkSize

    if end > len(logs) {
        end = len(logs)
    }

    temp := logs[i:end]  // Create a new slice for the chunk
    divided = append(divided, temp)  // Append the chunk to the divided slice
}
