Subject Re: [javascript] cant get timestamps in arrow 2.0
Date Thu, 17 Dec 2020 18:09:20 GMT
So, I figured out the issue here - I had to remove compression from the
pyarrow feather.write_feather(compression='uncompressed'). Is there any way
to read a compressed feather file in arrow js?
See the comment under the first answer here:
I couldn't find anything in the arrow docs or notebooks on this - I'm
assuming that's related to javascript compression libraries being so
