Thanks for the formatting.

Yes, my questions is not to compare InnoDB vs NDB, but about the two operation in each data engine.

Why the impact is so big, specially in NDB between those two.

What the Operation Insert seems to cost that much compare to just the update.

Should the first part of both being the same? Find if there is a record with that key? and if found do an update in both.

I understand the INSERT needs to validate all the constrains, but it seems the impact for NDB (for these very old version) is massive.
