### Fall back to the Zorkian metric client with feature gate

Since [v0.69.0](https://github.com/open-telemetry/opentelemetry-collector-contrib/releases/tag/v0.69.0), the Datadog exporter has switched to use the native metric client `datadog-api-client-go` for metric export instead of Zorkian client by default. While `datadog-api-client-go` fixed several issues that are present in Zorkian client, there is a performance regression with it compared to Zorkian client espeicially under high metric volume. If you observe memory or throughput issues in the Datadog exporter with `datadog-api-client-go`, you can configure the Datadog exporter to fall back to the Zorkian client by disabling the feature gate `exporter.datadogexporter.metricexportnativeclient`, e.g.
```
otelcol --config=config.yaml --feature-gates=-exporter.datadogexporter.metricexportnativeclient
```
Note that we are currently migrating the Datadog metrics exporter to use the metrics serializer instead. The feature flag `exporter.datadogexporter.metricexportnativeclient` will be deprecated and eventually removed in the future, following the [feature lifecycle](https://github.com/open-telemetry/opentelemetry-collector/tree/main/featuregate#feature-lifecycle).
