ClickHouse compressor

Simple program for data compression and decompression.

Examples

Compress data with LZ4:

$ ./clickhouse-compressor < input_file > output_file

Decompress data from LZ4 format:

$ ./clickhouse-compressor --decompress < input_file > output_file

Compress data with ZSTD at level 5:

$ ./clickhouse-compressor --codec 'ZSTD(5)' < input_file > output_file

Compress data with Delta of four bytes and ZSTD level 10.

$ ./clickhouse-compressor --codec 'Delta(4)' --codec 'ZSTD(10)' < input_file > output_file
