## Problem Moving the Logs Explorer to ClickHouse means users' saved BigQuery queries no longer run. <img width="2430" height="1010" alt="CleanShot 2026-06-29 at 11 36 04@2x" src="https://github.com/user-attachments/assets/ae0ab155-7d3d-4ae9-81c3-22bf3a88cf8c" /> ## Fix Rewrite the query with AI instead of a SQL transpiler. AI handles the long tail of nested fields and dialect differences far better than a rule-based rewriter, and it needs no extra runtime dependency. - `rewriteLogsSqlWithAI` posts the current query to `/api/ai/code/complete` with `dialect: 'clickhouse'`. The endpoint skips the Postgres schema and best-practices for that dialect and uses logs-specific instructions and model so the output is ClickHouse logs SQL (FROM `logs` + `source` filter, no `unnest` joins, nested fields read from `log_attributes['...']`). - The query's `source` is detected and its real `log_attributes` keys are fetched and passed to the model, so it maps to exact paths instead of guessing. - The rewrite runs in the background and is proposed as a side-by-side accept/discard diff in the editor. The AI Assistant panel is not opened. - Entry points: a banner shown only for legacy-looking queries (dismissal persisted), and a "Fix Query" button next to Field Reference. - The Field Reference drawers discover `log_attributes` keys from real data so the listed fields match what the source actually emits. ## Dependencies Built on top of #47265 (Logs Explorer -> OTEL endpoint) — that is the base branch of this PR. Merge #47265 first. Behind `otelLegacyLogs` (off by default). Part of DEBUG-145 (split from #47087). ## How to test - Open the Logs Explorer with a BigQuery logs query (the templates have some), click "Fix Query", and confirm the diff shows valid ClickHouse SQL. Accept it and confirm the applied query runs. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added an OTEL legacy logs workflow (behind a feature flag) with an interactive banner and a “Fix Query” ClickHouse rewrite action, including an accept/discard diff review overlay. * Introduced OTEL-aware field reference rendering with dynamic discovery of `log_attributes` keys and updated OTEL source insertion behavior. * Enabled dialect-aware SQL completion for ClickHouse logs, using logs-specific instructions and output constraints. * **Bug Fixes** * Improved rewrite flow validation and handling, including log source detection and cleanup of AI-generated SQL formatting. * **Tests** * Added Vitest coverage for rewrite prompt generation, detection/classification utilities, SQL fence stripping, OTEL field mapping, and OTEL log attribute key discovery. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Co-authored-by: Joshen Lim <joshenlimek@gmail.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.
