df['ROW_NUM'] = df.sort_values(by=['PART_NUM']).groupby(['CLAIM_NUM']).cumcount() + 1
that is equivalent to performing SQL's ROW_NUMBER PARTION BY syntax, where I can then filter to the first record in each grouping (ROW_NUMBER ==1).
http://ibis-project.org is working
this page works for me too. At the top of this page you can see the links to Getting started, Documentation, Community...
So the link to Documentation is not working for me.
And my bookmarks of ibis documentation also not accessible with 404 error (e.g. https://ibis-project.org/docs/backends/impala.html)
experimental
in the github page, I guess some features are missing , but is there a list of features that it should implement in order to be considered as "complete"?
