I’m excited to try out HTTP direct. I noticed this line in the docs:

If you have previously connected to Datomic via a VPC Endpoint Service, you will need to delete the VPC Endpoint service before installing a VPC Link for HTTP Direct.

If I am currently using a VPC Endpoint service to connect via the client api from another VPC, will I just need to delete and recreate the Endpoint service and recreate the Endpoint in the other VPC?

Thanks

Out of curiosity, why is HTTP Direct not available for Solo topologies?

5

HTTP Direct requires a Network Load Balancer. Solo does not have one.

It’d be great if there was the ability to add a NLB to the Solo topology.
