MySQL 8.0 Reference Manual Including MySQL NDB Cluster 8.0
The zlib_decompress utility decompresses mysqlpump output that was created using ZLIB compression.
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:
shell> zlib_decompress input_file
output_file
Example:
shell>mysqlpump --compress-output=ZLIB > dump.zlib
shell>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”.
