Redis CLI Verification

# Start the Redis CLI

# To see the redis cached key and value pair
$ KEYS *

To enable caching on any query, the query should be in following format

query = User.find({});
query.where("id", req.session.userId);
query.lean() # Lean is what instructs Redis to cache the query results
query.exec(function(err, userInfo){
    // Process the Query Results
});
