Description

What problem is being solved?

• The limit of contextual tuples per request is hardcoded to 100. Over the years, the contextual tuple limit has moved from 10, 20, then feat: bump max count of contextual tuples to 100 api#208.
• Some adopters pass every identity group as contextual tuples and easily exceed 100 (Contextual Tuple limit configuration openfga#3021).
• The CLI turns authorization model test fixtures (.fga.yaml) into contextual tuples, so large test suites hit the same cap.

How is it being solved?

• Make the contextual tuples limit configurable

What changes are made to solve it?

openfga/openfga#3352

References

• implements: feat: add RFC for configurable contextual tuple limit rfcs#39

Summary by CodeRabbit

• Documentation
  • Clarified that contextual tuples are limited by the configurable maxContextualTuples setting, which defaults to 100 and applies across supported request types.
  • Updated request-size guidance: request bodies must also fit within the configured gRPC message-size limit. The request-size limit is checked first, and oversized HTTP requests receive a 413 Request Entity Too Large response.

Walkthrough

The documentation adds the maxContextualTuples setting and clarifies that grpc.maxRecvMsgBytes also limits HTTP request bodies. It states the defaults, the contextual tuple limit’s scope, and the order in which the limits are checked.

Summary

Document request limits docs-site/getting-started/setup-openfga/configuration.mdx, docs-site/interacting/contextual-tuples.mdx

The configuration table adds maxContextualTuples, with a default of 100 and a requirement that it be greater than zero. The contextual tuple guidance describes its scope. Both documents state that grpc.maxRecvMsgBytes also limits HTTP request bodies; the contextual tuple guidance says the body limit is checked first. The configuration table notes that oversized bodies receive 413 Request Entity Too Large.

Full details: Title check

Explanation

The title "feat: Document the configurable contextual limit feature" matches the main change. The changeset documents the new maxContextualTuples setting (default 100, must be greater than zero) in the configuration reference and updates the contextual tuples page to describe the configurable limit and its interaction with grpc.maxRecvMsgBytes. The title is specific, short, and states the primary change from the developer's perspective.

Server behavior matches openfga/openfga#3352 (flag, env var, YAML key, default 100, minimum 1, scope incl. BatchCheck per check and Expand, 413 on oversized HTTP bodies).

Blocking:

1. The feature is unreleased: openfga/openfga#3352 and openfga/api#267 are both open. Every released server still rejects more than 100 contextual tuples via proto validation, regardless of config.
2. Both configuration.mdx edits are inside the generated table region, so they are misattributed to v1.20.0 and will be reverted by the next npm run build:config-page run.

CI is green on 7a711a20. Earlier failures came from the stale base and were fixed by the docs-next merge.

[OsmanMElsayed]

Thanks for the review @Siddhant-K-code 🙏. All comments addressed, except for the one related to adding a version callout as this is waiting for the feature implementation PRs to be shipped.

I liked how you automate the config documenation by pulling it from the server package 🙌

[Siddhant-K-code]

Re-reviewed fe37624b. The wording and the upstream schema move both look good, and the text matches openfga/openfga#3352 (per-check BatchCheck, InvalidArgument, body size checked first).

Still blocking:

1. Test deployment fails because of this PR: check:site-boundary reports missing native anchor #OPENFGA_MAX_CONTEXTUAL_TUPLES. The row was removed, so the link has no target until the table is regenerated.
2. openfga/openfga#3352 and openfga/api#267 are still open, so released servers (latest v1.22.1) still enforce a fixed 100.

Suggest converting this to draft until the release ships.

[Siddhant-K-code]

Once a release with openfga/openfga#3352 ships:

1. Merge the regenerated config table into docs-next (the nightly update-docs draft PR, or npm run build:config-page -- --release vX.Y.Z), then merge docs-next here. That adds the anchor and fixes Test deployment.
2. Add the version callout here, following getting-started/update-tuples.mdx, e.g. "Requires OpenFGA vX.Y.Z+. Earlier versions enforce a fixed limit of 100."
