What ORMs out there natively support sharding well? I use Django the most and whenever I look into Django sharding, I don't see very many options being kept up to date...
We've created a library at Citus to make rails sharding turn-key, activerecord-multi-tenant. We have a Django one in the works, if you want to take a look and give us any feedback on it please drop us a note. From what I've seen hibernate has some out of the box support, but we only have a few customers leveraging it so not as familiar with it.
