title: how to tackle large data in redis
body: <p>My pc have 3G memory,and I store data into redis.I write data to disk via dump.rdb. I found when dump.rdb is about 1.5G,redis will shut down,why that?</p>
  
  <p>and when I input <strong>info</strong> in redis-cli,I found all my memory are spent by redis.</p>
  
  <p>how to tackle that?</p>
  
  <p>I use <code>32bit, ubuntu 12.04.</code></p>
  
  <p>if I add more memory,32bit machine only can hold 4G memory,so if I will add more 5G data，how to tackle that much dat?</p>
  
  <p>thx guys.</p>
