4.8.3 zlib_decompress — Decompress mysqlpump ZLIB-Compressed Output

The zlib_decompress utility decompresses mysqlpump output that was created using ZLIB compression.

Note

If MySQL was configured with the -DWITH_ZLIB=system option, zlib_decompress is not built. In this case, the system openssl zlib command can be used instead.

Invoke zlib_decompress like this:

zlib_decompress input_file output_file

Example:

mysqlpump --compress-output=ZLIB > dump.zlib
zlib_decompress dump.zlib dump.txt

To see a help message, invoke zlib_decompress with no arguments.

To decompress mysqlpump LZ4-compressed output, use lz4_decompress. See Section 4.8.1, “lz4_decompress — Decompress mysqlpump LZ4-Compressed Output”.
