What is the difference between substr command from JedisCommands and java.lang.String
Redis’
substrcommand is performed in Redis server, so you don’t need the whole string in you Java client to perform the operation.E.g.: If it’s a long string (e.g.: 1G) you don’t need to fetch it all to get the first few bytes, reducing memory usage and the network connection between your Java client and Redis.
Another difference is that Java’s
substris about characters, while Redis’substris about bytes. That makes a huge difference when dealing with UTF-8 strings.
