I now pass divisions= based on the row counts in each row_group. The information on whether there are sorting columns and statistics in each piece are also available, so I can implement what you suggest.
from fastparquet.
Suggestions for what should should be in __repr__
/__str__
? I have an info, columns, dtypes, divisions (i.e., row numbers) and cats (i.e., partitions) properties currently available.
from fastparquet.
Location, size in bytes, columns or number of columns, dtypes? I wouldn't
worry about it near term though. I think we'll have more to say on this
topic after the project sees more use.
