lz4_decompress input_file output_file
The lz4_decompress utility decompresses mysqlpump output that was created using LZ4 compression.
If MySQL was configured with the -DWITH_LZ4=system option, lz4_decompress is not built. In this case, the system lz4 command can be used instead.
Invoke lz4_decompress like this:
shell> lz4_decompress input_file output_file
shell> mysqlpump --compress-output=LZ4 > dump.lz4 shell> lz4_decompress dump.lz4 dump.txt
To see a help message, invoke lz4_decompress with no arguments.
To decompress mysqlpump ZLIB-compressed output, use zlib_decompress. See zlib_decompress(1).
