Subject LZ4 support in Windows conda (py)arrow
Date Fri, 11 Jun 2021 08:37:57 GMT
In the matrix of pyarrow artifacts for [conda, conda-forge] x [linux,
windows], it seems all of them support LZ4, except (conda, windows). Is
there a known reason for this?

As I understand it, the conda Arrow builds are managed externally (by
Continuum?), so perhaps should get in touch with them - as might not have `
-DARROW_WITH_LZ4=ON`?

There errors at run-time look like,

...
    pa.CompressedInputStream(
  File "pyarrow\io.pxi", line 1208, in
pyarrow.lib.CompressedInputStream.__init__
  File "pyarrow\io.pxi", line 1579, in pyarrow.lib.Codec.__init__
  File "pyarrow\error.pxi", line 141, in
pyarrow.lib.pyarrow_internal_check_status
  File "pyarrow\error.pxi", line 118, in pyarrow.lib.check_status
pyarrow.lib.ArrowNotImplementedError: Support for codec 'lz4' not built

Cheers,
-Joris.
