Im thinking about doing the following and need suggestions if it makes sense to approach it this way. Basically since I am able to do queries in MongoDB and MongoDb is wicked fast at these since the hotspots of the data are cached in memory. I was thinking of storing data I would normally do a join from in mysql in mongoDB. While I am using memcached to store simple query results (for example a movie description page), for bigger stuff that requires more realtime/ondemand queries I was thinking about storing this in MongoDB. For example the view count for movies and who saw it, and doing analysis on it.

Hopefully I explained it clearly.

more info:

We dont want to keep writing to our mysql server on every rating like etc, MongoDB seemed like a good option to store the ratings,views of movies etc and then later on be able to do processing on that data. Whereas with Memcached data is not persisted and were unable to do queries

Thanks,
Faisal

    Memory caching alone is not a good reason to go with MongoDB. Any properly configured RDBMS will cache frequently used data in memory.

    What aspect of MySQL is currently limiting your performance? Do you have enough RAM in your server? Are your disks fast enough? Do you have a low latency cache device like an SSD configured appropriately?
