Implement efficient data utils methods for Tables.MatrixTable
There is a need to implement efficient selectrows
and selectcols
methods for Tables.MatrixTable
table type. The current data utils methods only have efficient fallbacks for DataFrame
table type, but we could easily add efficient methods for Tables.MatrixTable
type after this issue get resolved.
This would avoid materializing wide matrix tables as a NamedTuple
which the Julia compiler has issues handling.

Agreed.
Waiting for:
- [ ] resolution of https://github.com/JuliaData/Tables.jl/issues/281
