title: Will Redis queue up hset commands for numerous requests?
body: <p>Say I have 100 requests coming in every second and for each query, a hash value needs to be extracted and then, the same hash needs to be updated sort of like:</p>
  
  <p>redis.hget 'value', 'user-123'
  redis.hset 'value', 'user-123', JSON.generate({:number_of_visits => 15})</p>
  
  <p>What happens if there's a ton of read\writes per second? </p>
  
  <p>Will redis just queue up both the hget and hset commands and they'll all execute in order they came in? Will it slow down the hgets the more commands come in?</p>
