Do you mean "info memory" in redis? jedis.info() function can get the memory info. jedis only have info function , no "info memory" commands

Do you mean "info memory" in redis?
Nope, I believe he's asking about the MEMORY (https://redis.io/commands/memory-help) commands.
^ yeah those ones.
Yeah, ideally MEMORY
should be supported just like some other commands.
For now, just use INFO memory
command. Something like
String s = jedis.info("memory");
Properties props = Properties.load(new StringReader(s));
props.get("used_memory");

@gkorland what happened to this commit did it never make it? Seems like the commit is dangling and never made it into master. https://github.com/redis/jedis/commit/d1a692c79bca7b8434e8aac4b31f58cd54f972eb
@billoneil This is weird. Thanks for noticing.
Resolved by #2279 & #2908

While using memoryUsage(key)method of Jedis i am getting this following error "errorMessage": "ERR unknown command 'memory', with args beginning with: USAGE" is it possible that this method is not allowed on AWS ElastiCache
is it possible that this method is not allowed on AWS ElastiCache
@pratik-patil-polestar ask AWS ElastiCache. thank you
I want to get the memory usage per key that is being by redis cache. I tried using the Connection class method sendCommand but to no luck because i don't think it has existing functionality for the Memory commands.
