support for arrow data frame #195

Closed jangorecki closed 11 months ago

jangorecki commented 11 months ago

Documentation doesn't mention arrow so I assume slider will not support arrow data frame format. By supporting arrow I mean redirecting sliders calls to an arrow's own implementation of rolling functions, when called on arrow data frame. So arrow df don't have to be pulled into R df to do the rolling computation. Are there any plans for that?

Does arrow have rolling functions to map to? 🤔

jangorecki commented 11 months ago

No idea...

I believe all of the work would have to be done in arrow for this, so I'm going to close in favor of https://github.com/apache/arrow/issues/36849
