https://issues.apache.org/jira/browse/ARROW-17159
@zhztheplayer can you take a look at #13830 and let me know your thoughts? In particular, that PR puts the slicing information into FileFragment
while this one puts the information into FileSource
. At the moment I think FileFragment
might be more usable and also similar to the pyarrow function that splits a dataset into more fragments (multiple fragments per file) using row groups.
Closing because it has been untouched for a while, in case it's still relevant feel free to reopen and move it forward 👍
