Minor Changes

Implement new directives to allow getting and setting context. This allows resolvers to reference and access data referenced by entities that exist in the GraphPath that was used to access the field. The following example demonstrates the ability to access the prop field within the Child resolver. (#2988)

type Query {
  p: Parent!
}
type Parent @&#8203;key(fields: "id") @&#8203;context(name: "context") {
  id: ID!
  child: Child!
  prop: String!
}
type Child @&#8203;key(fields: "id") {
  id: ID!
  b: String!
  field(a: String @&#8203;fromContext(field: "$context { prop }")): Int!
}

🐛 Fixes

Improve error message produced when a subgraph response doesn't include an expected `content-type` header value (Issue #5359)

To improve a common debuggability challenge when a subgraph response doesn't contain an expected content-type header value, the error message produced will include additional details about the error.

Some examples of the improved error message:

    HTTP fetch failed from 'test': subgraph response contains invalid 'content-type' header value "application/json,application/json"; expected content-type: application/json or content-type: application/graphql-response+json

    HTTP fetch failed from 'test': subgraph response does not contain 'content-type' header; expected content-type: application/json or content-type: application/graphql-response+json

Update `apollo-compiler` for two small improvements (PR #5347)

Updated our underlying apollo-rs dependency on our apollo-compiler crate to bring in two nice improvements:

Fix validation performance bug

Adds a cache in fragment spread validation, fixing a situation where validating a query with many fragment spreads against a schema with many interfaces could take multiple seconds to validate.
Remove ariadne byte/char mapping

Generating JSON or CLI reports for apollo-compiler diagnostics used a translation layer between byte offsets and character offsets, which cost some computation and memory proportional to the size of the source text. The latest version of ariadne allows us to remove this translation.

📃 Configuration

Rename the telemetry selector which obtains the GraphOS operation id (PR #5337)

Renames a misnamed trace_id selector introduced in v1.48.0 to the value which it actually represents which is an Apollo GraphOS operation ID, rather than a trace ID. Apologies for the confusion! Unfortunately, we aren't able to produce an Apollo GraphOS trace ID at this time.

If you want to access this operation ID selector, here is an example of how to apply it to your tracing spans:

telemetry:
  instrumentation:
    spans:
      router:
        "studio.operation.id":
            studio_operation_id: true

This can be useful for more easily locating the operation in GraphOS' Insights feature and finding applicable traces in Studio.

[!IMPORTANT]
If you have enabled Distributed query plan caching, this release has a Federation version bump, which will result in ordinary/expected changes to the hashing algorithm used for the distributed cache keys. On account of this, you should anticipate additional cache regeneration cost when updating to this version while the new hashing algorithm comes into service.

🚀 Features

Demand control preview (PR #5317)

⚠️ This is a preview for an Enterprise feature of the Apollo Router. It requires an organization with a GraphOS Enterprise plan. If your organization doesn't currently have an Enterprise plan, you can test out this functionality with a free Enterprise trial.

As a preview feature, it's subject to our Preview launch stage expectations and configuration and performance may change in future releases.

Demand control allows you to control the cost of operations in the router, potentially rejecting requests that are too expensive that could bring down the Router or subgraphs.

### Demand control enabled, but in measure mode.
preview_demand_control:
  enabled: true

### `measure` or `enforce` mode. Measure mode will analyze cost of operations but not reject them.
  mode: measure

  strategy:

### Static estimated strategy has a fixed cost for elements and when set to enforce will reject
### requests that are estimated as too high before any execution takes place.
    static_estimated:

### The assumed returned list size for operations. This should be set to the maximum number of items in graphql list
      list_size: 10

### The maximum cost of a single operation.
      max: 1000

Telemetry is emitted for demand control, including the estimated cost of operations and whether they were rejected or not.
Full details will be included in the documentation for demand control which will be finalized before the next release.

Ability to include Apollo Studio trace ID on tracing spans (Issue #3803), (Issue #5172)

Add support for a new trace ID selector kind, the apollo trace ID, which represents the trace ID on Apollo GraphOS Studio.

An example configuration using trace_id: apollo:

telemetry:
  instrumentation:
    spans:
      router:
        "studio.trace.id":
            trace_id: apollo

Add ability for router to deal with query plans with contextual rewrites (PR #5097)

Adds the ability for the router to execute query plans with context rewrites. A context is generated by the @fromContext directive, and each context maps values in the collected data JSON onto a variable that's used as an argument to a field resolver. To learn more, see Saving and referencing data with contexts.

⚠️ Because this feature requires a new version of federation, v2.8.0, distributed caches will need to be repopulated.

🐛 Fixes

Fix custom attributes for spans and histogram when used with `response_event` (PR #5221)

This release fixes multiple issues related to spans and selectors:

Custom attributes based on response_event in spans are properly added.
Histograms using response_event selectors are properly updated.
Static selectors that set a static value are now able to take a Value.
Static selectors that set a static value are now set at every stage.
The on_graphql_error selector is available on the supergraph stage.
The status of a span can be overridden with the otel.status_code attribute.

As an example of using these fixes, the configuration below uses spans with static selectors to mark spans as errors when GraphQL errors occur:

telemetry:
  instrumentation:
    spans:
      router:
        attributes:
          otel.status_code:
            static: error
            condition:
              eq:
              - true
              - on_graphql_error: true
      supergraph:
        attributes:
          otel.status_code:
            static: error
            condition:
              eq:
              - true
              - on_graphql_error: true

Fix instrument incrementing on aborted request when condition is not fulfilled (PR #5215)

Previously when a telemetry instrument was dropped it would be incremented even if the associated condition was not fulfilled. For instance:

telemetry:
  instrumentation:
    instruments:
      router:
        http.server.active_requests: false
        http.server.request.duration: false
        "custom_counter":
          description: "count of requests"
          type: counter
          unit: "unit"
          value: unit

### This instrument should not be triggered as the condition is never true
          condition:
            eq:
              - response_header: "never-received"
              - static: "true"

In the case where a request was started, but the client aborted the request before the response was sent, the response_header would never be set to "never-received",
and the instrument would not be triggered. However, the instrument would still be incremented.

Conditions are now checked for aborted requests, and the instrument is only incremented if the condition is fulfilled.

🛠 Maintenance

Send query planner and lifecycle metrics to Apollo (PR #5267, PR #5270)

To enable the performance measurement of the router's new query planner implementation, the router transmits to Apollo the following new metrics:

apollo.router.query_planning.* provides metrics on the query planner that help improve the query planning implementation.
apollo.router.lifecycle.api_schema provides feedback on the experimental Rust-based API schema generation.
apollo.router.lifecycle.license provides metrics on license expiration that help improve the reliability of the license check mechanism.

These metrics don't leak any sensitive data.

📚 Documentation

Add Rhai API constants reference

The Rhai API documentation now includes a list of available constants that are available in the Rhai runtime.

By @bnjjj in https://github.com/apollographql/router/pull/5189

🧪 Experimental

GraphQL instruments (PR #5215, PR #5257)

This PR adds experimental GraphQL instruments to telemetry.

The new instruments are configured in the following:

telemetry:
  instrumentation:
    instruments:
      graphql:
### The number of times a field was executed (counter)
        field.execution: true
### The length of list fields (histogram)
        list.length: true
### Custom counter of field execution where field name = name
        "custom_counter":
          description: "count of name field"
          type: counter
          unit: "unit"
          value: field_unit
          attributes:
            graphql.type.name: true
            graphql.field.type: true
            graphql.field.name: true
          condition:
            eq:
              - field_name: string
              - "name"
### Custom histogram of list lengths for topProducts
        "custom_histogram":
          description: "histogram of review length"
          type: histogram
          unit: "unit"
          attributes:
            graphql.type.name: true
            graphql.field.type: true
            graphql.field.name: true
          value:
            field_custom:
              list_length: value
          condition:
            eq:
              - field_name: string
              - "topProducts"

Using the new instruments consumes significant performance resources from the router. Their performance will be improved in a future release.

Large numbers of metrics may also be generated by using the instruments, so make sure to not incur excessively large APM costs.

⚠ Use these instruments only in development. Don't use them in production.

🚀 Features

Support telemetry selectors with errors (Issue #5027)

The router now supports telemetry selectors that take into account the occurrence of errors. This capability enables you to create metrics, events, or span attributes that contain error messages.

For example, you can create a counter for the number of timed-out requests for subgraphs:

telemetry:
  instrumentation:
    instruments:
      subgraph:
        requests.timeout:
          value: unit
          type: counter
          unit: request
          description: "subgraph requests containing subgraph timeout"
          attributes:
            subgraph.name: true
          condition:
            eq:
              - "request timed out"
              - error: reason

The router also can now compute new attributes upon receiving a new event in a supergraph response. With this capability, you can fetch data directly from the supergraph response body:

telemetry:
  instrumentation:
    instruments:
      acme.request.on_graphql_error:
        value: event_unit
        type: counter
        unit: error
        description: my description
        condition:
          eq:
          - MY_ERROR_CODE
          - response_errors: "$.[0].extensions.code"
        attributes:
          response_errors:
            response_errors: "$.*"

By @bnjjj in https://github.com/apollographql/router/pull/5022

Add support for `status_code` response to Rhai (Issue #5042)

The router now supports response.status_code on the Response interface in Rhai.

Examples using the response status code:

Converting a response status code to a string:

if response.status_code.to_string() == "200" {
    print(`ok`);
}

Converting a response status code to a number:

if parse_int(response.status_code.to_string()) == 200 {
    print(`ok`);
}

By @bnjjj in https://github.com/apollographql/router/pull/5045

Add gt and lt operators for telemetry conditions (PR #5048)

The router supports greater than (gt) and less than (lt) operators for telemetry conditions. Similar to the eq operator, the configuration for both gt and lt takes two arguments as a list. The gt operator checks that the first argument is greater than the second, and the lt operator checks that the first argument is less than the second. Other conditions such as gte, lte, and range can be made from combinations of gt, lt, eq, and all.

Expose busy timer APIs (PR #4989)

The router supports public APIs that native plugins can use to control when the router's busy timer is run.

The router's busy timer measures the time spent working on a request outside of waiting for external calls, like coprocessors and subgraph calls. It includes the time spent waiting for other concurrent requests to be handled (the wait time in the executor) to show the actual router overhead when handling requests.

The public methods are Context::enter_active_request and Context::busy_time. The result is reported in the apollo_router_processing_time metric

For details on using the APIs, see the documentation for enter_active_request.

🐛 Fixes

Reduce JSON schema size and Router memory footprint (PR #5061)

As we add more features to the Router the size of the JSON schema for the router configuration file continutes to grow. In particular, adding conditionals to telemetry in v1.46.0 significantly increased this size of the schema. This has a noticeable impact on initial memory footprint, although it does not impact service of requests.

The JSON schema for the router configuration file has been optimized from approximately 100k lines down to just over 7k.

This reduces the startup time of the Router and a smaller schema is more friendly for code editors.

Prevent query plan cache collision when planning options change (Issue #5093)

The router's hashing algorithm has been updated to prevent cache collisions when the router's configuration changes.

[!IMPORTANT]
If you have enabled Distributed query plan caching, this release changes the hashing algorithm used for the cache keys. On account of this, you should anticipate additional cache regeneration cost when updating between these versions while the new hashing algorithm comes into service.

The router supports multiple options that affect the generated query plans, including:

defer_support
generate_query_fragments
experimental_reuse_query_fragments
experimental_type_conditioned_fetching
experimental_query_planner_mode

If distributed query plan caching is enabled, changing any of these options results in different query plans being generated and cached.

This could be problematic in the following scenarios:

The router configuration changes and a query plan is loaded from cache which is incompatible with the new configuration.
Routers with different configurations share the same cache, which causes them to cache and load incompatible query plans.

To prevent these from happening, the router now creates a hash for the entire query planner configuration and includes it in the cache key.

5xx internal server error responses returned as GraphQL structured errors (PR #5159)

Previously, the router returned internal server errors (5xx class) as plaintext to clients. Now in this release, the router returns these 5xx errors as structured GraphQL (for example, {"errors": [...]}).

Internal server errors are returned upon unexpected or unrecoverable disruptions to the GraphQL request lifecycle execution. When these occur, the underlying error messages are logged at an ERROR level to the router's logs.

Custom telemetry events not created when logging is disabled (PR #5165)

The router has been fixed to not create custom telemetry events when the log level is set to off.

An example configuration with level set to off for a custom event:

telemetry:
  instrumentation:
    events:
      router:

### Standard events
        request: info
        response: info
        error: info

### Custom events
        my.disabled_request_event:
          message: "my event message"
          level: off # Disabled because we set the level to off
          on: request
          attributes:
            http.request.body.size: true

Ensure that batch entry contexts are correctly preserved (PR #5162)

Previously, the router didn't use contexts correctly when processing batches. A representative context was chosen (the first item in a batch of items) and used to provide context functionality for all the generated responses.

The router now correctly preserves request contexts and uses them during response creation.

Validate enum values in input variables (Issue #4633)

The router now validates enum values provided in JSON variables. Invalid enum values result in GRAPHQL_VALIDATION_FAILED errors.

By @Geal in https://github.com/apollographql/router/pull/4753

Strip dashes from `trace_id` in `CustomTraceIdPropagator` (Issue #4892)

The router now strips dashes from trace IDs to ensure conformance with OpenTelemetry.

In OpenTelemetry, trace IDs are 128-bit values represented as hex strings without dashes, and they're based on W3C's trace ID format.

This has been applied within the router to trace_id in CustomTraceIdPropagator.

Note, if raw trace IDs from headers are represented by uuid4 and contain dashes, the dashes should be stripped so that the raw trace ID value can be parsed into a valid trace_id.

Add support of custom events defined by YAML for telemetry (Issue #4320)

Users can now configure telemetry events via YAML
to log that something has happened (e.g. a request had errors of a particular type) without reaching for Rhai or a custom plugin.

Events may be triggered on conditions and can include information in the request/response pipeline as attributes.

Here is an example of configuration:

telemetry:
  instrumentation:
    events:
      router:

### Standard events
        request: info
        response: info
        error: info

Ability to ignore auth prefixes in the JWT plugin

The router now supports a configuration to ignore header prefixes with the JWT plugin. Given that many application headers use the format of Authorization: <scheme> <token>, this option enables the router to process requests for specific schemes within the Authorization header while ignoring others.

For example, you can configure the router to process requests with Authorization: Bearer <token> defined while ignoring others such as Authorization: Basic <token>:

authentication:
  router:
    jwt:
      header_name: authorization
      header_value_prefix: "Bearer"
      ignore_mismatched_prefix: true

If the header prefix is an empty string, this option is ignored.

Support conditions on custom attributes for spans and a new selector for GraphQL errors (Issue #4336)

The router now supports conditionally adding attributes on a span and the new on_graphql_error selector that is set to true if the response body contains GraphQL errors.

An example configuration using condition in attributes and on_graphql_error:

telemetry:
  instrumentation:
    spans: 
      router: 
        attributes:    
          otel.status_description: 
            static: "there was an error"
            condition:

🐛 Fixes

Federation v2.7.5 (PR #5064)

This brings in a query planner fix released in v2.7.5 of Apollo Federation. Notably, from its changelog:

Fix issue with missing fragment definitions due to generateQueryFragments. (#2993)

An incorrect implementation detail in generateQueryFragments caused certain queries to be missing fragment definitions, causing the operation to be invalid and fail early in the request life-cycle (before execution). Specifically, subsequent fragment "candidates" with the same type condition and the same length of selections as a previous fragment weren't correctly added to the list of fragments. An example of an affected query is:
```
query {
  t {
    ... on A {
      x
      y
    }
  }
  t2 {
    ... on A {
      y
      z
    }
  }
}
```
In this case, the second selection set would be converted to an inline fragment spread to subgraph fetches, but the fragment definition would be missing

Use supergraph schema to extract authorization info (PR #5047)

The router now uses the supergraph schema to extract authorization info, as authorization information may not be available on the query planner's subgraph schemas. This reverts the authorization changes made in PR #4975.

By @tninesling in https://github.com/apollographql/router/pull/5047

Filter fetches added to batch during batch creation (PR #5034)

Previously, the router didn't filter query hashes when creating batches. This could result in failed queries because the additional hashes could incorrectly make a query appear to be committed when it wasn't actually registered in a batch.

This release fixes this issue by filtering query hashes during batch creation.

Use `subgraph.name` attribute instead of `apollo.subgraph.name` (PR #5012)

In the router v1.45.0, subgraph name mapping didn't work correctly in the Datadog exporter.

The Datadog exporter does some explicit mapping of attributes and was using a value apollo.subgraph.name that the latest versions of the router don't use. The correct choice is subgraph.name.

This release updates the mapping to reflect the change and fixes subgraph name mapping for Datadog.

📚 Documentation

Document traffic shaping default configuration (PR #4953)

The documentation for configuring traffic shaping has been updated to clarify that it's enabled by default with preset values. This setting has been the default since PR #3330, which landed in v1.23.0.

By @bnjjj in https://github.com/apollographql/router/pull/4953

🧪 Experimental

Experimental type conditioned fetching (PR #4748)

This release introduces an experimental configuration to enable type-conditioned fetching.

Previously, when querying a field that was in a path of two or more unions, the query planner wasn't able to handle different selections and would aggressively collapse selections in fetches. This resulted in incorrect plans.

Enabling the experimental_type_conditioned_fetching option can fix this issue by configuring the query planner to fetch with type conditions.

experimental_type_conditioned_fetching: true # false by default

🐛 Fixes

Correct v1.44.0 regression in query plan cache (PR #5028)

Correct a critical regression that was introduced in v1.44.0 which could lead to execution of an incorrect query plan. This issue only affects Routers that use distributed query plan caching, enabled via the supergraph.query_planning.cache.redis.urls configuration property.

By @o0Ignition0o in https://github.com/apollographql/router/pull/5028

Use entire schema when hashing an introspection query (Issue #5006)

Correct a different hashing bug which impacted introspection queries which was also introduced in v1.44.0. This other hashing bug failed to account for introspection queries, resulting in introspection results being misaligned to the current schema. This issue only affects Routers that use distributed query plan caching, enabled via the supergraph.query_planning.cache.redis.urls configuration property.

This release fixes the hashing mechanism by adding the schema string to hashed data if an introspection field is encountered. As a result, the entire schema is taken into account and the correct introspection result is returned.

Fix subgraph name mapping of Datadog exporter (PR #5012)

Previously in the router v1.45.0, subgraph name mapping didn't work correctly in the router's Datadog exporter. The exporter used the incorrect value apollo.subgraph.name for mapping attributes when it should have used the value subgraph.name. This issue has been fixed in this release.

[!CAUTION]

This version has a critical bug impacting users of distributed query plan caching. See the Fixes in v1.45.1 for details. We highly recommend using v1.45.1 (or newer) or v1.43.2 over v1.45.0.

🚀 Features

Query validation process with Rust (PR #4551)

The router has been updated with a new Rust-based query validation process using apollo-compiler from the apollo-rs project. It replaces the Javascript implementation in the query planner. It improves query planner performance by moving the validation out of the query planner and into the router service, which frees up space in the query planner cache.

Because validation now happens earlier in the router service and not in the query planner, error paths in the query planner are no longer encountered. Some messages in error responses returned from invalid queries should now be more clear.

We've tested the new validation process by running it for months in production, concurrently with the JavaScript implementation, and have now completely transitioned to the Rust-based implementation.

By @Geal in https://github.com/apollographql/router/pull/4551

Add support for SHA256 hashing in Rhai (Issue #4939)

The router supports a new sha256 module to create SHA256 hashes in Rhai scripts. The module supports the sha256::digest function.

An example script that uses the module:

fn supergraph_service(service){
    service.map_request(|request|{
        log_info("hello world");
        let sha = sha256::digest("hello world");
        log_info(sha);
    });
}

By @lleadbet in https://github.com/apollographql/router/pull/4940

Subgraph support for query batching (Issue #2002)

As an extension to the ongoing work to support client-side query batching in the router, the router now supports batching of subgraph requests. Each subgraph batch request retains the same external format as a client batch request. This optimization reduces the number of round-trip requests from the router to subgraphs.

Also, batching in the router is now a generally available feature: the experimental_batching router configuration option has been deprecated and is replaced by the batching option.

Previously, the router preserved the concept of a batch until a RouterRequest finished processing. From that point, the router converted each batch request item into a separate SupergraphRequest, and the router planned and executed those requests concurrently within the router, then reassembled them into a batch of RouterResponse to return to the client. Now with the implementation in this release, the concept of a batch is extended so that batches are issued to configured subgraphs (all or named). Each batch request item is planned and executed separately, but the queries issued to subgraphs are optimally assembled into batches which observe the query constraints of the various batch items.

To configure subgraph batching, you can enable batching.subgraph.all for all subgraphs. You can also enable batching per subgraph with batching.subgraph.subgraphs.*. For example:

batching:
  enabled: true
  mode: batch_http_link
  subgraph:

### Enable batching on all subgraphs
    all:
      enabled: true

batching:
  enabled: true
  mode: batch_http_link
  subgraph:

### Disable batching on all subgraphs
    all:
      enabled: false

### Configure (override) batching support per subgraph
    subgraphs:
      subgraph_1:
        enabled: true
      subgraph_2:
        enabled: true

Note: all can be overridden by subgraphs. This applies in general for all router subgraph configuration options.

To learn more, see query batching in Apollo docs.

🐛 Fixes

Update `rustls` to v0.21.11, the latest v0.21.x patch (PR #4993)

While the Router does use rustls, RUSTSEC-2024-0336 (also known as CVE-2024-32650 and GHSA-6g7w-8wpp-frhj) DOES NOT affect the Router since it uses tokio-rustls which is specifically called out in the advisory as unaffected.

Despite the lack of impact, we update rustls version v0.21.10 to rustls v0.21.11 which includes a patch.

🧪 Experimental

Experimental: Introduce a pool of query planners (PR #4897)

The router supports a new experimental feature: a pool of query planners to parallelize query planning.

You can configure query planner pools with the supergraph.query_planning.experimental_parallelism option:

supergraph:
  query_planning:
    experimental_parallelism: auto # number of available CPUs

Its value is the number of query planners that run in parallel, and its default value is 1. You can set it to the special value auto to automatically set it equal to the number of available CPUs.

You can discuss and comment about query planner pools in this GitHub discussion.

Experimental: Rust implementation of Apollo usage report field generation (PR 4796)

The router supports a new experimental Rust implementation for generating the stats report keys and referenced fields that are sent in Apollo usage reports. This implementation is one part of the effort to replace the router-bridge with native Rust code.

The feature is configured with the experimental_apollo_metrics_generation_mode setting. We recommend that you use its default value, so we can verify that it generates the same payloads as the previous implementation.
