title: Entering large string (1 MB) as keyfor a key gives exception
body: <p>According to the specification of redis size of the string can be 512 MB (<a href="https://groups.google.com/forum/#!topic/redis-db/HH4z-8mHNLM" rel="nofollow">link</a>)</p>
  
  <p>I tried to insert a large string of approximately 1 MB in size using the following command</p>
  
  <pre><code>cat command.txt | redis-cli --pipe
  </code></pre>
  
  <p>where the content of command.txt is <code>SET k &lt;large string&gt;</code></p>
  
  <p>I am getting following error
     ERR Protocol error: too big inline request</p>
  
  <p>Little bit digging around the net shows that the size of a reuqest is limited by <code>REDIS_INLINE_MAX_SIZE</code> whose value is fixed as (1024*64) or 64KB.</p>
  
  <p>Is there any way to change that or is there a better way to send large string into redis</p>
