Add function to compute bulk load plan for file when splits are not known. #5971
Description
Is your feature request related to a problem? Please describe.
When table splits are not known for a file that will be bulk imported it would be useful to have a function to compute a load plan for the file. Currently their is no easy way to do this in the public API.
Describe the solution you'd like
Offer a function like LoadPlan LoadPlan.compute(URI file) similar to this function that computes a load plan based on the files first and last row. This return a load plan with a range type of FILE.
Describe alternatives you've considered
If the RFile public API offered an efficient way to get the last key in the file, this would provide another way to accomplish creating the load plan for this case.
