4.8.1 lz4_decompress — Decompress mysqlpump LZ4-Compressed Output

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: 

shell> lz4_decompress input_file output_file

Example: 

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 Section 4.8.3, “zlib_decompress — Decompress mysqlpump ZLIB-Compressed Output”.
