Ivan Stoiev updated FLINK-38946:
--------------------------------
Summary: Allow AWS VPC Endpoint/GCP Cloud Private Service Connect for
Datadog integration (was: Update Datadog API endpoint from app.datadoghq to
api.datadoghq)
> Allow AWS VPC Endpoint/GCP Cloud Private Service Connect for Datadog
> integration
> --------------------------------------------------------------------------------
>
> Key: FLINK-38946
> URL: https://issues.apache.org/jira/browse/FLINK-38946
> Project: Flink
> Issue Type: Improvement
> Components: Runtime / Metrics
> Reporter: Ivan Stoiev
> Priority: Minor
>
> The current implementation of the {{DatadogHttpClient}} in the
> {{flink-metrics-datadog}} module uses {{app.datadoghq.com}} (or regional
> variants) as the base URL for sending metrics.
> Using {{api.datadoghq}} is the official supported URL prefix for API-based
> integrations, whereas {{app.datadoghq}} is a legacy URL for this purpose.
> Updating this endpoint provides two significant benefits:
> # {*}Official Support{*}: It aligns the Flink integration with Datadog's
> supported API host standards. This is particularly relevant for the following
> calls:
> * *Submit Metrics:*
> [{{/api/v1/series}}|https://docs.datadoghq.com/api/latest/metrics/#submit-metrics]
> * *Validate API Key:*
> [{{/api/v1/validate}}|https://docs.datadoghq.com/api/latest/authentication/#validate-api-key]
> # *Private Networking Support:* Many modern cloud networking features, such
> as *AWS VPC endpoints (PrivateLink)* and {*}GCP Cloud Private Service
> Connect{*}, specifically require the use of the {{api.datadoghq}} endpoint to
> route traffic privately. Using {{app.datadoghq}} prevents these integrations
> from working in restricted network environments.

> * [GCP Private Service Connect
> Documentation|https://docs.datadoghq.com/agent/guide/gcp-private-service-connect/?site=eu]
> *Proposed Change:* In {{{}DatadogHttpClient.java{}}}, the base URLs should be
> updated from: {{[https://app.datadoghq.%s/...]}} to:
> {{[https://app.datadoghq.%s/...]}}
> This change ensures that metric submissions follow the recommended path for
> programmatic access and enables compatibility with private connectivity
> solutions.
