## Problem Sustained memory overcommitment is one of the failure patterns that most often leads to databases being killed when the system runs out of memory. Today the database report only shows used memory against total RAM, which hides the kernel's commit accounting: a project can sit far above its commit limit (RAM plus swap, adjusted by the overcommit ratio) and the dashboard gives no signal until something breaks. A combined chart with swap, overcommitment, and main memory was considered too dense, and a standalone swap chart was not useful enough on its own. Linear: [DEBUG-119](https://linear.app/supabase/issue/DEBUG-119) ## Fix Adds a separate "Memory commitment" chart between the existing memory usage and swap charts. It plots `ram_commit_used` (Committed_AS) as the main series with `ram_commit_limit` (CommitLimit) as the max-value threshold line, so values approaching or crossing the limit are visually obvious. Backend support for the two new metric attributes ships in supabase/platform#33321. ## How to test - Wait for the platform PR (supabase/platform#33321) to deploy so the two new attributes are accepted by the infra monitoring endpoint. - Open any project, navigate to Database -> Reports. - Confirm the new "Memory commitment" chart appears between "Memory usage" and "Swap usage". - Confirm the chart shows two series: the committed memory bars/area and a max line for the commit limit. - Hover the legend and the chart to confirm the tooltips read clearly. - Confirm the time range selector and chart sync (`syncId: 'database-reports'`) keep this chart aligned with the others. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Added comprehensive guide for interpreting memory commitment patterns in telemetry reports, including component breakdown, chart pattern guidance, and actionable recommendations. * **New Features** * Added memory commitment chart to database observability dashboard, displaying RAM commitment usage and limits. * Extended monitoring API to support new RAM commitment metrics. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 4.7 <noreply@anthropic.com>

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.
- 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.
