Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Lastly, update the main function to create a cache with a specified capacity and test the TTL and LRU features.”

A block of code is set as follows:

func main() {
    cache := NewCache(5) // Setting capacity to 5 for LRU
    cache.startEvictionTicker(1 * time.Minute)
}

Any command-line input or output is written as follows:

go run main.go -port=:8080 -peers=http://localhost:8081
