## Problem Image layer generation could block L0 compactions for a long time. ## Summary of changes * Refactored the return value of `create_image_layers_for_*` functions to make it self-explainable. * Preempt image layer generation in `Try` mode if L0 piles up. Note that we might potentially run into a state that only the beginning part of the keyspace gets image coverage. In that case, we either need to implement something to prioritize some keyspaces with image coverage, or tune the image_creation_threshold to ensure that the frequency of image creation could keep up with L0 compaction. --------- Signed-off-by: Alex Chi Z <chi@neon.tech> Co-authored-by: Erik Grinaker <erik@neon.tech>
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.
