Does Datomic team have any schedule on this feature?
We do not publish a roadmap of Datomic feature development. The product team has made a commitment to stewarding the product according to technical best practices and does not want to run the risk of customers developing against promised functionality that may turn out to be a bad idea for the product as a whole or reprioritized in favor of more critical features. We welcome and encourage technical feedback and feature requests. Those are taken seriously and made part of the product management decision-making.
