             Summary: [JS] read compressed (LZ4/LZTD) files
                 Key: ARROW-11261
                 URL: https://issues.apache.org/jira/browse/ARROW-11261
             Project: Apache Arrow
          Issue Type: Improvement
          Components: JavaScript
    Affects Versions: 2.0.0
            Reporter: eric mauviere


arrow compressed files, such as one produced with R arrow::write_feather are 
much smaller than those created with write_ipc_stream.

And of course on the web it makes a big difference.

But i can't properly read such 'feather' files with Arrow js (arrow.Table.from).

For instance dictionary values are not properly decoded
