write_parquet: Write Parquet file with optional encryption

In rcdf: A Comprehensive Toolkit for Working with Encrypted Parquet Files

Write Parquet file with optional encryption

Description

This function writes a dataset to a Parquet file. If an encryption key is provided, the data will be encrypted before writing. Otherwise, the function writes the data as a regular Parquet file without encryption.

Usage

write_parquet(data, path, ..., encryption_key = NULL)

Arguments

data	A data frame or tibble to write to a Parquet file.
path	The file path where the Parquet file will be written.
...	Additional arguments passed to 'arrow::write_parquet()' if no encryption key is provided.
encryption_key	A list containing 'aes_key' and 'aes_iv'. If provided, the data will be encrypted using AES before writing to Parquet.

Value

None. The function writes the data to a Parquet file at the specified 'path'.

Examples

data <- mtcars
key <- "5bddd0ea4ab48ed5e33b1406180d68158aa255cf3f368bdd4744abc1a7909ead"
iv <- "7D3EF463F4CCD81B11B6EC3230327B2D"

temp_dir <- tempdir()

rcdf::write_parquet(
  data = data,
  path = file.path(temp_dir, "mtcars.parquet"),
  encryption_key = list(aes_key = key, aes_iv = iv)
)

unlink(file.path(temp_dir, "mtcars.parquet"), force = TRUE)
