How to import large mysql database (innodb , myisam tables) to MySQL NDB cluster

Question

Mysqlcluster used:- GA 7.4, Centos 7

I have 30GB each physical memory in 2 datanodes and SSD 200GB each but the database size(cumulative size of multiple db's belonging to free radius ) is around 55GB. Is it possible to migrate my mysql database(myisam/innodb mix tables) to ndb cluster ? i appreciate any useful links suggestions.

Answer 1

Yes, it is possible. But is it really what do you want? Question sounds to me like you found some new and cool called NDB cluster and want to use it without any deeper knowledge. NDB is storage engine, do you know you can do all necessary modification to your DB structure?
