Depth validation src/graphql/handler.js, package.json |
The handler applies query-depth and introspection-depth validation. The query-depth limit defaults to 8, and rejected checks are reported as GraphQL errors. Runtime dependencies include @escape.tech/graphql-armor-max-depth. |
Depth-limit deployment configuration bin/deploy-bamboo.sh, cdk/graphql/lib/graphql-stack.ts, cdk/graphql/package.json, cdk/graphql-docs/package.json, cdk/graphql-infrastructure/package.json |
The deployment script passes MAX_QUERY_DEPTH from Bamboo. The GraphQL Lambda environment uses MAX_QUERY_DEPTH with a default of 8, and bundling specifies the root lockfile. The CDK package manifests update dependency ranges. |
Collection granule counts

|---|---|
Count contract and selection parsing src/types/collection.graphql, src/cmr/concepts/collection.js, src/utils/parseRequestedFields.js, src/utils/isGranuleCountOnlySelection.js, src/utils/__tests__/* |
Collection inputs add includeGranuleCounts, and Collection adds the nullable granuleCount field. Request parsing identifies count-only granule selections, requests collection granule counts, and includes granuleCount in requested fields. Tests cover selection parsing and requested-field results. |
Collection search and count resolution src/datasources/collection.js, src/resolvers/collection.js, src/resolvers/__tests__/collection.test.js |
Collection search merges additional parameters into its search parameters. For count-only selections, the granules resolver returns the parent collection count. Other selections continue through granule search. Tests cover both paths. |

Deep introspection requests can still exceed the configured query-depth limit, so that safeguard should be corrected before merging.

Explanation
The title names two changes: GraphQL query depth rules and granule counts for collections. Both are present in the changeset: handler.js adds validation rules, and the collection types, resolvers, and CMR parameter list add granuleCount and includeGranuleCounts. The title is the GQL-161 ticket prefix followed by a long, two-part phrasing, so it is not concise, but it is related to the main change and covers the primary points.
Full details: Description check
-
Explanation
The description follows the template sections: Overview (feature, solution, impacted areas), Testing (reproduction steps, attachments), and Checklist. It explains both the query depth guard and granule counts, with clear reproduction steps. Gaps: the Testing environment and collection placeholders are unfilled (<e.g. local / SIT / UAT> and <collection concept ID...>). The checklist shows that automated tests were not marked as added, though the changeset includes new test files. The documentation checkbox is also unchecked. The description also includes unrelated items (dependency bumps, the dotenvx move, and a GQL-160 note) that are not in the template but are reasonably scoped.
Resolution
Optional improvements: fill in the Testing placeholders (environment and collection concept ID). Confirm the checklist items for automated tests and unit test results, since the changeset adds test files. Consider noting the documentation status. Consider moving the dependency and dotenvx notes into a clearly labeled section.

- Line 132: Update the UMM collection key mapping and sharedKeys handling for
granuleCount so parseRequestedFields includes it in revision queries; preserve
support for include_granule_counts in UMM JSON responses. Add a regression test
covering a revision query that selects granuleCount.
Review comments at @src/graphql/handler.js:
- Around line 142-143: Update the maxDepthRule configuration in the GraphQL
handler to apply the configured maxQueryDepth to introspection selections by
disabling its default introspection exclusion. Preserve the existing depth-limit
value and verify standard schema-introspection clients remain supported.
- Line 143: Validate maxQueryDepth as a positive integer before passing it to
the depth rule; when invalid, reject the configuration or use the existing
documented default of 8 so the rule never receives NaN.

See if we can thread this for calls such as ` collections(params: $params) {
count
items {
granules {
count
}`
}
}
automatically, that way we get the performance boosts across, making this more consistent and we won't have to update MMT if we do that

NaN check needed
const parsedDepth = parseInt(maxQueryDepth, 10)
const n = Number.isNaN(parsedDepth) ? 8 : parsedDepth

I can add this. It seems a bit unnecessary to me. The only time this could be an issue is if we put in abc into bamboo but, added

Spread order lets the heuristic always win over an explicit value: additionalVariableParameters (set by parseRequestedFields based on selection shape) is spread after params, so includeGranuleCounts: false passed explicitly by a client is silently overwritten to true whenever the query selects a count-only granules { count }. Suggest only applying the heuristic default when the client didn't explicitly set it:
const fetchParams = {
...params,
...additionalVariableParameters,
...(params.includeGranuleCounts !== undefined && {
includeGranuleCounts: params.includeGranuleCounts
})
}

I feel like we should override that value if its using that count signature we need it otherwise we can't get the counts I could add a comment. I don't know what the use-case is of passing that as false and adding in the granule { counts } I could see it but, then the optimization won't really work

consider renaming to additionalSearchParams just so we don't get this confused with the concept, Variable
Overview
What is the feature?
Two related changes tied to GQL-161:
includeGranuleCountsargument, which populates a newgranuleCountfield. This lets MMT get counts directly instead of making a separate granule request per collection. as seen herehttps://github.com/nasa/mmt/blob/main/static/src/js/operations/queries/getCollections.js#L15What is the Solution?
