Hi, Thanks for your replies.
In our case, we can't implement NOSQL solution. Thats requires modify/check all our application and all services (Including FreeRADIUS that I'm not sure if it's compatible). Andrew, I have heard about people that has a lot of data, more than me. I know that MySQL support this amount but in this case and thinking in the future, I have this problem with my architecture; how can I grow in database servers without delete rows in the tables. I have checked slow queries and now there aren't. These tables are serving queries from FreeRADIUS service. For example, SUMs, COUNTS, nomal SELECTs ... Always with a where condition. Excuse me, what is the meaning of IMO? Thanks. Regards, Antonio.
