Does anyone know in which language DynamoDB is implemented? I've read somewhere that SimpleDB is done in Erlang. Is that the case with DynamoDB as well? I've been reading about Ets and Dets in Erlang and it makes me wonder whether they have anything to do with either of these data stores.

I haven't seen it written anywhere, but judging by the __type in errors like this, I would say Java:

  {"__type":"com.amazon.coral.validate#ValidationException",
  "message":"One or more parameter values were invalid:
  The provided key size does not match with that of the schema"}
