Grant Nguyen created ARROW-6960:
-----------------------------------
Summary: Add information about zstd/lz4 codec installation and
linkages for R users
Key: ARROW-6960
URL: https://issues.apache.org/jira/browse/ARROW-6960
Project: Apache Arrow
Issue Type: Improvement
Components: R
Affects Versions: 0.15.0
Environment: Windows 10
Reporter: Grant Nguyen
When I attempt to write a parquet file using lz4, zstd, or brotli compression
using R arrow 0.15.0, I am unable to do so due to the codec support not being
built (example below).
{code:java}
> arrow::write_parquet(payout_strategy, sink =
> "records_test_lz4.parquet",compression = "lz4")
Error in parquet___arrow___FileWriter__WriteTable(self, table, chunk_size) :
Arrow error: IOError: Arrow error: NotImplemented: LZ4 codec support not
built{code}
I believe that the error is generated through
[https://github.com/apache/arrow/blob/master/cpp/src/arrow/util/compression.cc#L124-L145],
but I am not sure how to call
{code:java}
install.packages("arrow"){code}
in R to enable the ARROW_WITH_ZSTD/LZ4/BROTLI flags, or whether I should be
doing installing zstd separately from arrow and then doing something pre- or
post-install to link zstd with arrow. From
[https://github.com/apache/arrow/issues/1209], it appears that zstd support has
been added to arrow and parquet in general, and the [R package
readme|[https://github.com/apache/arrow/tree/master/r]] notes "On macOS and
Windows, installing a binary package from CRAN will handle Arrow's C++
dependencies for you", but I get the sense that does not apply to zstd.
Is there guidance as to how to enable zstd and other compression codecs prior
to or after downloading the R arrow package? Could this be added to the R
documentation somewhere for future reference?
