Should I use cassandra in 100,000 users project ? In mysql 5 have full text search and partition table. I'm starting to make Question and answer system like stackoverflow with CodeIgniter. It's move from vbulletin to new system. In old vbulletin have around 100,000 users and total post is around 80,000. In next 3 or 4 year, users and posts will be more and more. So, Should I use cassandra instead of mysql 5 ?

If I use cassandra, I need to change gridserver in mediatemple to DV server in mediatemple. Cassandra is not built in hosting system. So, I must use VPS or DV server.

If I use mysql 5, hosting is not problem but how about speed and search. Btw, What database using in Stack Over ?
