write_parquet_zstd: Write a zstd-compressed parquet file

In adamleejohnson/r-tools: AJ's R Tools

Description

A basic wrapper around arrow::write_parquet().

Usage

write_parquet_zstd(
  x,
  sink,
  compression_level = 6,
  write_statistics = FALSE,
  ...
)

Arguments

x	data.frame, RecordBatch, or Table
sink	A string file path, URI, or OutputStream, or path in a file system (SubTreeFileSystem)
compression_level	compression level. Meaning depends on compression algorithm
write_statistics	Specify if we should write statistics. Default TRUE
...	Arguments passed on to arrow::write_parquet chunk_size chunk size in number of rows. If NULL, the total number of rows is used. version parquet version, "1.0" or "2.0". Default "1.0". Numeric values are coerced to character. compression compression algorithm. Default "snappy". See details. use_dictionary Specify if we should use dictionary encoding. Default TRUE data_page_size Set a target threshold for the approximate encoded size of data pages within a column chunk (in bytes). Default 1 MiB. use_deprecated_int96_timestamps Write timestamps to INT96 Parquet format. Default FALSE. coerce_timestamps Cast timestamps a particular resolution. Can be NULL, "ms" or "us". Default NULL (no casting) allow_truncated_timestamps Allow loss of data when coercing timestamps to a particular resolution. E.g. if microsecond or nanosecond data is lost when coercing to "ms", do not raise an exception properties A ParquetWriterProperties object, used instead of the options enumerated in this function's signature. Providing properties as an argument is deprecated; if you need to assemble ParquetWriterProperties outside of write_parquet(), use ParquetFileWriter instead. arrow_properties A ParquetArrowWriterProperties object. Like properties, this argument is deprecated.
