This study is not a definitive benchmark of data reduction, but it offers a glimpse of MongoDB compression offerings and effects of the different compression algorithms. It is important to test the impacts of compression in your own environment.
The default snappy compression offers a good balance between compression savings, system resource utilization, and ingestion performance. The zlib and zstd algorithms are better at reducing the data but at a cost of higher overhead. Regardless of which software compression you choose, PowerStore advanced hardware-based data reduction offers additional space savings to the MongoDB environment without any performance overhead.
