Slice chunking in Go

by

You don’t need to make new slices, just append slices of logs to the divided slice.

var divided [][]string

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

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

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

    divided = append(divided, logs[i:end])
}

fmt.Printf("%#v\n", divided)
