Real-time compression algorithm and software.

Zstandard is a real-time compression algorithm, providing high compression ratios. It offers a very wide range of compression / speed trade-off, while being backed by a very fast decoder (see benchmarks below). It also offers a special mode for small data, called dictionary compression, and can create dictionaries from any sample set. Zstandard library is provided as open source software using a BSD license.

What sort of transformations could make a large sum of data of 3D arrays more compressible with zstd?

There is not much sources on this,I would like ideas and ways of thinking that will enable my understanding.

If you lose trained dictionary for ZST archive, can you still decompress it?

I see that you can have a trained sample for specific file types to increase compression ratio, if you lose that dictionary are you still able to decompress the archive or is it essentially corrupted?
