There seem to be well maintained docs here - the README for storey doesn't explain many of the classes. https://docs.mlrun.org/en/latest/api/storey.transformations.html

pyarrow is at 3 which is compatible with newer versions of numpy and on linux comes as manylinux wheel (prebuilt)

The ~= definition to all dependencies is kinda unclear. What is the lowest numpy version that can be used with storey package? Which storey version supports numpy==1.18.5?

I catch exception during writing data to on-line feature store via MLRun see exception (I made performance tests)
