Pandas h5py driver='core' support for Pandas HDFStore.

Is it possible to use the driver argument for HDFStore? Pandas 0.21rc1. THank you.

Comment From: TomAugspurger

Could you give an example for those unfamiliar with what h5py drivers are?

pandas HDFStore is built around pytables, not h5py, so I suspect this won't be possible.

Thank you.

you can pass it as a kwarg on construction

but h5py is incompat with PyTables at a link level so likely won’t work
