+We are providing a path with auto generated arrow files for testing purposes,
change that at your convenience.
+
+Compressed file generated through this code example:
+
+.. code:: python
+
+ import pandas as pd
+ import pyarrow as pa
+
+ pd.DataFrame({'key': range(4)}).to_feather('lz4.arrow', compression='lz4')
+ pd.DataFrame({'key': range(4)}).to_feather('zstd.arrow', compression='zstd')
+
+.. note::
+
+ Java Vector module offer read files without compression codec, in case
reading
+ compressed files is required consider to also add Java Compression module
+ dependency.
Review Comment:
```suggestion
The ``arrow-vector`` module can only read uncompressed files by itself.
Add
a dependency on ``arrow-compression`` to also be able to read compressed
files.
```

Review Comment:
Is it possible to provide a write-compressed-file example too?
