OpenZL delivers high compression ratios while preserving high speed, a level of performance that is out of reach for generic compressors.

Do I understand correctly that this has all the building blocks which make up various lossless compression schemes (dictionaries, run length encoding, delta encoding, etc) and kit bashes them together for your specific dataset?

I was under the impression that modern file formats and compression schemes already kind of do that as part of the normal compression process, so I was a little surprised by how much they beat some of the competition in their benchmarks.
