--------------------------------------
Summary: Loading of feather file created with recent pandas fails
in JS arrow lib
Key: ARROW-13818
URL: https://issues.apache.org/jira/browse/ARROW-13818
Project: Apache Arrow
Issue Type: Bug
Components: JavaScript
Affects Versions: 5.0.0
Reporter: Daniel Bachler
Attachments: metadata-tiny.feather
The attached dataframe with a few records fails to load properly when using the
JS arrow library. When inspecting the loaded content, the string values seem to
include characters before the actual start of the string. Loading a large file
like this is also extremely slow.
The file was generated using the latest pandas and pyarrow versions. To rule
out platform dependent issues with writing the file, the same file was computed
and written on Windows 10 and linux. Both files were binary identical and
loaded without issues in pandas.
