Grouping mutations

[al...@ceid.upatras.gr]

I am reading mutate(), and I see that it simply loops through the list of
mutations and sends them off individually. Consider a scenario where I
call mutate() with a list of thousands of mutations, most of them going to
a few nodes.

Is there a way to group them into a few messages per node? If there is, I
can't find it, but I can't imagine why it isn't implemented that way, I
feel I am missing something. Please explain!

Nope, you're right, it's all individual mutations past the StorageProxy level.

Interested to see your results if you experiment with grouping things up.
