Feature previews

Users can access and test upcoming capabilities before they are generally available through enabling feature flags in DCT. These feature previews are intended for evaluation and feedback, and may change or be removed in a future release.

Use caution when enabling feature flag capabilities in production environments. Delphix Support for these features will not be provided.

Prerequisites

Before enabling a feature preview, make sure the following requirements are met:

Delphix telemetry must be set up and active, which allows Delphix to understand which features are being tested and how they are used.
You have received the feature flag secret code from your Delphix Account Team.
You have access to the API for your DCT deployment.

Enable feature flags

If telemetry is not yet configured, follow the instructions in Setting up telemetry. Telemetry must be enabled before you can activate any feature previews.
Access the Swagger UI for your DCT environment. This is typically available at: https://<dct-hostname>/api
In the Swagger UI, locate the /management/properties API. Use the operation to enable a feature preview.
1. Enter the secret code you received from your Account Team in the request body. It should follow this format:
  Copy
```
{
  "feature_flags": [
    "VERY_SECRET_CODE"
  ]
}
```
2. Execute the request to apply the feature flag.
(Optional) Some feature flags require a restart of DCT to apply the configuration. Use the following command:
1. For Kubernetes deployments, replace <namespace> of the following with the namespace where DCT is deployed.
  Copy
```
kubectl rollout restart deployment dct-services -n <namespace>
```
2. For Appliance deployments, follow your hypervisors restart process.

Feedback

If you encounter issues or have feedback about a feature preview, contact your Delphix Account Team. Your input during the preview stage helps guide future development and general availability.

Please note, Delphix Support does not support feature flag capabilities.
