title: fit mysql db in memory
body: <p>I am using Redis database where we store the navigational information. These data must be persistent and should be fetched faster. I don't have more than 200 MB data in this data set.</p>
  
  <p>I face problem when writing admin modules for redis db and I really missing the sql schema and power of django style admin modules.</p>
  
  <p>Now I am thinking of using MySQL. The requirement is, I want the persistent database but the data can be loaded into the memory like redis so that I can do the SQL queries REALLY faster.</p>
  
  <p>Is it possible to use MySQL in persistent mode and instruct MySQL to use the memory for querying purpose? What is the best suitable MySQL DB where I do not worry much on consistencies where our writes are very few.</p>
