About

Improvements to be mainlined from https://github.com/pyveci/supertask/blob/19316e2/supertask/store/cratedb.py. The support for binary data types is being emulated by serializing them to STRING using base64. In that way, pickled data can be stored and retrieved without further ado.

Keep in mind that CrateDB also supports BitString type, but I don't think that's what we want here, right?

Right. Here, it is about providing an emulation for a BLOB-type column. However, expanding type support to include the BIT type will be nice to have for the sake of completeness. So far, I didn't need it, but I am sure others will.
