LZ4_DECOMPRESS(1)

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

    lz4_decompress is deprecated as of MySQL 8.0.34; expect it to be removed in a future version of MySQL. This is because the associated mysqlpump utility is deprecated as of MySQL 8.0.34.

    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).
