DataMemory needs to be at least %50 free

[Marc Epstein]

Hi

Does datamemory for the ndb cluster need to be at least %50 free in order to do an alter table?

For instance, if I want to drop a column on a ndb table, it will copy that table to a temporary table, which then uses up the rest of the datamemory space.

Anyway around this or do I always need to make sure that I have that amount of memory free for a schema update?

Thanks,

Marc
