🚀 Features

Add configurability of span attributes in logs (Issue #​5540)

The router supports a new telemetry.exporters.logging.stdout.format.json.span_attributes option that enables you to choose a subset of all span attributes to display in your logs.

When span_attributes is specified, the router searches for the first attribute in its input list of span attributes from the root span to the current span and attaches it to the outermost JSON object for the log event. If you set the same attribute name for different spans at different levels, the router chooses the attributes of child spans before the attributes of parent spans.

For example, if you have spans that contains span_attr_1 attribute and you only want to display this span attribute:

telemetry:
  exporters:
     logging:
       stdout:
         enabled: true
         format: 
           json:
             display_span_list: false
             span_attributes:
               - span_attr_1

Example output with a list of spans:

{
  "timestamp": "2023-10-30T14:09:34.771388Z",
  "level": "INFO",
  "fields": {
    "event_attr_1": "event_attr_1",
    "event_attr_2": "event_attr_2"
  },
  "target": "event_target",
  "span_attr_1": "span_attr_1"
}

Add a histogram metric tracking evaluated query plans (PR #​5875)

The router supports the new apollo.router.query_planning.plan.evaluated_plans histogram metric to track the number of evaluated query plans.

You can use it to help set an optimal supergraph.query_planning.experimental_plans_limit option that limits the number of query plans evaluated for a query and reduces the time spent planning.

🐛 Fixes

Fix Datadog sampling (PR #​5788)

The router's Datadog exporter has been fixed so that traces are sampled as intended.

Previously, the Datadog exporter's context may not have been set correctly, causing traces to be undersampled.

📃 Configuration

General availability of Apollo usage report generation (#​5807)

The router's Apollo usage report generation feature that was previously experimental is now generally available.

If you used its experimental configuration, you should migrate to the new configuration options:

• telemetry.apollo.experimental_apollo_metrics_reference_mode is now telemetry.apollo.metrics_reference_mode
• telemetry.apollo.experimental_apollo_signature_normalization_algorithm is now telemetry.apollo.signature_normalization_algorithm
• experimental_apollo_metrics_generation_mode has been removed because the Rust implementation (the default since router v1.49.0) is generating reports identical to the previous router-bridge implementation

The experimental configuration options are now deprecated. They are functional but will log warnings.

Helm: Enable easier Kubernetes debugging with heaptrack (Issue #​5789)

The router's Helm chart has been updated to help make debugging with heaptrack easier.

Previously, when debugging multiple Pods with heaptrack, all Pods wrote to the same file, so they'd overwrite each others' results. This issue has been fixed by adding a hostname to each output data file from heaptrack.

Also, the Helm chart now supports a restartPolicy that enables you to configure a Pod's restart policy. The default value of restartPolicy is Always (the same as the Kubernetes default).

📚 Documentation

Document OpenTelemetry information for operation limits (PR #​5884)

The router's docs for operation limits now describe using telemetry to set operation limits and logging values.
