Iteration with multipart key

[creadone]

Hi Dima,

I started driver Sophia.cr for Sophia on Crystal Lang. In near future i want to build TSDB over Sophia.cr for use in monitoring and alerting for own projects.

I tried but did not understand C code which support iteration by multipart key. I found driver Sophy for Python where Coleifer implemented Json, MsgPack and UUID types. It is beautiful and gives good opportunities, and I would like to implement the same types and little more.

Do I understand correctly that Sophia pack and store multipart key as bytes with delimiter (in scheme) and unpacks during the iteration process? How can I participate in this process? Could you explain this?
