gunzip_file: Decompress a gzip file to a destination path

In quak: Query 'Azure Data Lake Storage Gen2' with 'DuckDB'

Decompress a gzip file to a destination path

Description

Streams src (a gzip-compressed file) through gzfile() into dest, fully closing both connections before returning. Closing the output connection flushes R's internal buffer to disk; skipping that step can leave the trailing bytes — where a .duckdb_extension stores its metadata footer — unwritten, yielding a corrupt file.

Usage

gunzip_file(src, dest)

Arguments

src	Character scalar. Path to the gzip-compressed source file.
dest	Character scalar. Path to write the decompressed output to.

Value

Invisibly returns dest.
