## What kind of change does this PR introduce? Docs update: states disk limits as per-size minimums and aligns burst copy across pages. Follow-up to #49996 (compute descriptions). Fixes PROD-658 ## What is the current behavior? - The disk limits table and surrounding prose describe a narrower set of configurations than a compute size can run on - Burst thresholds are inconsistent across pages (three different variants), and one section contradicts itself - Burst is described as CPU behavior, when the burst users observe is disk IO ## What is the new behavior? - `shared-data/compute-disk-limits.ts`: Medium baseline throughput adjusted to 39 MB/s: the lowest value across configurations - `compute-and-disk`: disk limits presented as minimums ("at least"); burst described as disk IO drawing on a disk IO budget; consistent thresholds: burst available up to 2XL, baseline equals maximum from 8XL - Troubleshooting guides (`exhaust-disk-io`, `failed-to-retrieve-tables`, `interpreting-supabase-grafana-io-charts`) aligned to the same threshold; `failed-to-retrieve-tables` keeps the ~30-minutes-per-day burst window with the corrected size range - Section anchors unchanged ## Self-review - Values verified against the AWS EBS-optimized performance data (`describe-instance-types`) for every configuration per size; content cross-checked with the internal runbooks (linked in PROD-658) - `supa-mdx-lint`: no findings in changed files - `pnpm build:guides-markdown` clean; generated `.md` exports show the new values and prose - All changed pages verified rendering in the local dev app - `pnpm typecheck` passes (shared-data + docs) - Note: `compute-disk-limits.ts` also feeds Studio (disk validation, IO budget tooltips). The only value change (Medium 43 → 39 MB/s) surfaces there as one chart tooltip label; conservative direction. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit - **Documentation** - Clarified the differences between shared and dedicated CPU resources. - Updated disk I/O guidance to explain baseline and burst limits as minimums. - Documented disk I/O bursting for compute sizes up to 2XL, including expected duration and limitations. - Clarified that 8XL and larger compute sizes have consistent performance without burst capacity. - Updated the documented baseline throughput for medium compute resources. <!-- end of auto-generated comment: release notes by coderabbit.ai -->

Maintainers
If you are a maintainer of any tools in the Supabase ecosystem, you can use this site to provide documentation for the tools & libraries that you maintain.
DocSpec
We use documentation specifications which can be used to generate human-readable docs.
- OpenAPI: for documenting API endpoints.
- SDKSpec (custom to Supabase): for SDKs and client libraries.
- ConfigSpec (custom to Supabase): for configuration options.
- CLISpec (custom to Supabase): for CLI commands and usage.
The benefit of using custom specifications is that we can generate many other types from a strict schema (eg, HTML and manpages). It also means that we can switch to any documentation system we want. On this site we use Next.js, but on Supabase's official website, we use a custom React site and expose only a subset of the available API for each tool.
