⏱️ Scheduled rollout

Overview

Scheduled rollout offer a structured, multi-stage approach to flag deployment, automating the rollout to specific environments and audiences.

At each stage happening on a specific date, you can modify your feature flags as you want, allowing to change the target audience of your flag.
While this sounds deceptively straightforward, it unlocks the potential for users to create complex release strategies by scheduling the incremental steps in advance.

For example, you may want to turn a feature ON for internal testing tomorrow and then enable it for your ‘beta’ user segment four days later.

Define a scheduled rollout

To use a scheduled rollout, you need to set the scheduledRollout field in your flag configuration.

This field is an array of steps, each step is a map with a date field and the other fields are the fields you want to update in your flag.

Format

info

You can change any fields that are available on your flag. Since your configuration has not been changed manually, it does not trigger any notifier.

Field	Description
steps	The only mandatory field in a step is the date. If no date is provided the step will be skipped. The other attributes of your step are what you want to update your flag, so every field available in the flag format can be updated. The new value in a field will override the existing one.

Example

In this example, the flag will be update multiple times:

1. We will add a targeting rule to target beta users at 2020-04-10T00:00:00.1+02:00.
2. We will update the query of this rule later to target non-beta users at 2022-05-12T15:36:00.1+02:00.
