Joshen Lim ea909e998b Local only: skip loading destinations if ETL API is not set up (#47031)
## Context

> [!IMPORTANT]  
> Changes in this PR only apply to the local environment - there should
not be any changes to staging (nor production)

Given that read replicas currently sit under database replication, the
UI currently waits for replication destinations to load before rendering
the page. However for local development, setting up of the ETL API isn't
necessary nor applicable for everyone so this indirectly adds friction
if we just want to work with read replicas.

## Changes involved
- Opting to skip retrying fetching ETL related requests if the error
returned is "replication API URL is not configured"
  - This is indicative that the local platform isn't set up for ETL yet
- ^ Database replication page will hence not wait for ETL requests to
succeed before finally rendering the UI
  - Node diagram will also then render properly (just read replicas)
- Add a small admonition to visualize this

/>

## To test
- Will only be able to test locally - basically just head over to the
database replication page (unless you somehow already have ETL API set
up locally)
- But can also verify that there's no changes on staging preview

Community & Support

  • Community Forum. Best for: help with building, discussion about database best practices.
  • GitHub Issues. Best for: bugs and errors you encounter using Supabase.
  • Email Support. Best for: problems with your database or infrastructure.
  • Discord. Best for: sharing your applications and hanging out with the community.

How it works

Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.

Architecture

Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.

Architecture

  • Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
  • Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
  • PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
  • GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
  • Storage a RESTful API for managing files in S3, with Postgres handling permissions.
  • pg_graphql a PostgreSQL extension that exposes a GraphQL API.
  • postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
  • Kong is a cloud-native API gateway.

Client libraries

Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
