------------------------------------
Summary: [R] Unrecognized compression type: LZ4 on Windows (was:
Unrecognized compression type: LZ4 on Windows)
> [R] Unrecognized compression type: LZ4 on Windows
> -------------------------------------------------
>
> Key: ARROW-10850
> URL: https://issues.apache.org/jira/browse/ARROW-10850
> Project: Apache Arrow
> Issue Type: Bug
> Components: R
> Affects Versions: 2.0.0
> Environment: Windows 10, R 3.6.2, RStudio 1.3.1073
> Reporter: Chris Kennedy
> Priority: Major
> Labels: LZ4
>
> Hello,
> I have recently re-installed Arrow from CRAN in R 3.6.2 and it no longer can
> import a feather file with LZ4 compression (whereas in previous months this
> worked fine):
> {code:java}
> > data = suppressWarnings(arrow::read_feather("blah.feather"))
> {code}
> {noformat}
> Error in ipc___feather___Reader__Read(self, columns) : Invalid: Unrecognized
> compression type: LZ4{noformat}
> I have attempted to install from source but continue to receive this error.
> According to the documentation though shouldn't the CRAN package also have
> LZ4 support? Is it possible that the CRAN build has lost LZ4 support? My
> feather file was created in pandas.
> If I install version 1.0.1 I can import the data correctly:
> {code:java}
> devtools::install_version("arrow", version = "1.0.1"){code}
> Happy to send over any other information that could be helpful, and apologies
> if I am making some mistake on my end.
> Thanks,
> Chris
