Hi lists,

I am trying to build ndb with two data nodes in a group. My current database size is mixed with myisam and innodb. size of them are

innodb 2.4 GB  
myisam 1.6 GB

I tried to calculate the Datamemory and Indexmemory with the perl script ndb\_size.pl comes with the mysql. It generated like the following

Parameter Minimum Requirements

- indicates greater than default

DataMemory(KB) 26912096\*  
IndexMemory(KB) 463704\*

does that mean should I have 25GB of RAM to store Datas in memory and and for index 452MB of ram?

please clear me is that really KB in size? and will it take this much ram to store all of them?
