will neon.tech support scaling to zero? like no cost for compute?
Neon is still in Technical Preview and only available with a free-tier.
Currently, a compute node scales down to zero after 5 minutes of inactivity. You can find more about the compute lifecycle here Compute Lifecycle — Neon Docs.
Scaling down to zero is enabled by default in the free-tier. In the future, we plan to allow users to disable the feature to always keep a compute node running. Users will also not be charge for inactive compute instances.
