- Add ComputeSpec flag `offload_lfc_interval_seconds` controlling whether LFC should be offloaded to endpoint storage. Default value (None) means "don't offload". - Add glue code around it for `neon_local` and integration tests. - Add `autoprewarm` mode for `test_lfc_prewarm` testing `offload_lfc_interval_seconds` and `autoprewarm` flags in conjunction. - Rename `compute_ctl_lfc_prewarm_requests_total` and `compute_ctl_lfc_offload_requests_total` to `compute_ctl_lfc_prewarms_total` and `compute_ctl_lfc_offloads_total` to reflect we count prewarms and offloads, not `compute_ctl` requests of those. Don't count request in metrics if there is a prewarm/offload already ongoing. https://github.com/neondatabase/cloud/issues/19011 Resolves: https://github.com/neondatabase/cloud/issues/30770
Local Development Control Plane (neon_local)
This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command. This is a convenience to invoke
the neon_local binary.
Note: this is a dev/test tool -- a minimal control plane suitable for testing code changes locally, but not suitable for running production systems.
Example: Start with Postgres 16
To create and start a local development environment with Postgres 16, you will need to provide --pg-version flag to 3 of the start-up commands.
cargo neon init --pg-version 16
cargo neon start
cargo neon tenant create --set-default --pg-version 16
cargo neon endpoint create main --pg-version 16
cargo neon endpoint start main
Example: Create Test User and Database
By default, cargo neon starts an endpoint with cloud_admin and postgres database. If you want to have a role and a database similar to what we have on the cloud service, you can do it with the following commands when starting an endpoint.
cargo neon endpoint create main --pg-version 16 --update-catalog true
cargo neon endpoint start main --create-test-user true
The first command creates neon_superuser and necessary roles. The second command creates test user and neondb database. You will see a connection string that connects you to the test user after running the second command.
