It seems that current design of Modin DataFrame “wrapper” (the
modin.pandas.DataFrame thingy) is rather rigid in terms of indexing - it seems to support one-dimensional indexers along each of the axis, at least in terms of doing a
.loc on them.
I think we should discuss the steps to implement the support for multi-dimensional indices, as adding it seems to be a nontrivial task (from what I saw it touches a lot of small places around the code).
Maybe I’m misunderstanding something here?
