Is it worth using NDB cluster, solely for robust circular replication?

[Ron Arts]

Hi,

I am testing with a multi-master setup over 3 DCs. This is just for a small, low-volume database. The DC ops oppose allocating many (.. more than one..) VMs for this purpose.

Is it worth using NDB cluster for this scenario? Even if all processes run on the same physical node? From the docs I infer that circular replication is more robust than other storage engines. ("Deferring constraints in this way is currently supported only by NDB. Thus, updates of unique keys when replicating from NDB to a different storage engine such as MyISAM or InnoDB are still not supported." - is this relevant?)

Or isn't it worth it, and I should just move to regular MySQL master-master

Thanks
