OpenZL delivers high compression ratios while preserving high speed, a level of performance that is out of reach for generic compressors. OpenZL takes a description of your data and builds from it a specialized compressor optimized for your specific format. OpenZL consists of a core library and tools to generate specialized compressors - all compatible with a single universal decompressor. It is designed for engineers that deal with large quantities of specialized datasets (like AI workloads for example) and require high speed for their processing pipelines.
