NAME

lz4_decompress − decompress mysqlpump LZ4−compressed output

SYNOPSIS

lz4_decompress input_file output_file

DESCRIPTION

The lz4_decompress utility decompresses mysqlpump output that was created using LZ4 compression.

Note
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:

lz4_decompress input_file output_file

Example:

mysqlpump −−compress−output=LZ4 > dump.lz4
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).
