Datomic is designed to use only one transactor [1]. It uses a single node for write operations, but potentially many nodes for read operations.

Yeah the datomic support team seems to be focused on paying clients and only provides some responses to general questions. I think this forum has been set up with the hopes that community members will provide help within the community. And it’s a good idea however the community is just not that big so not every question gets answered or is answered in a timely fashion.
