Please note that RethinkDB does not support Etags or Transactions (for multiple items) and as such cannot be used as actor state store. I have just completed the work to make this component Beta, but have determined that Etags are not truly supported. Please do not use this component as actor state store. We will be updating the docs to make this clear.
