Implement efficient data utils methods for Tables.MatrixTable

Open OkonSamuel opened this issue 2 years ago • 1 comments

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.
