Partition Sets (Legacy)
Admin access or Domain access to property with feature access to message/scenario partition set management
A partition set allows your organization to divide end-users who visit a property into one or more distinct partitions (groupings) who can receive different messaging scenarios. By utilizing a partition set, you can A/B test different scenarios on property visitors and/or manage a controlled rollout of your messaging experience. In this article, we will cover how partition sets are divided (bucket start/end) and use cases for partition sets.

Partition %

The message scenario that is shown to your end-user is determined by the Sourcepoint messaging library running on the property the end-user visits. Your organization can determine what percentage of end-users are shown each message.
In the example below two messages have been created with different themes. A partition set is a collection of partitions with a total partition size is 100%. Your organization should set each partition to a message and a scenario. The 'Partition %' is the percentage of end-users who are shown a particular message.

The messaging scenario that is surfaced to your end-user is determined by which bucket the end-user has been assigned to when they visit a property. Each end-user that visits a property with the Sourcepoint messaging library running on it will get assigned a random value from 0 to 999. This value is stored in the end-user's cookie and persists until the user deletes the cookie.
By setting the start and end bucket values of each partition, you can control the percentage of end-users who are served a certain message scenario.
The bucket values will determine what percentage of users will experience the selected scenario. For example, 0 - 999 means that 100% of users will experience the scenario whereas 0-499 means 50% of users will experience the scenario.
In the below example. we have evenly split the partition set into two partitions. The first partition (0-499, 50%) will receive the default scenario while the second partition (500-999, 50%) will receive the test2 scenario.

Use Cases

A/B Testing

Partition sets can be used to A/B test messaging experiences where a certain percentage of users see one experience and another percentage of users see a different experience. This requires that you set up as many scenarios as you have partition groups.
In the example below, the partition set has 2 partitions: Group A and Group B. Group A users will be assigned a bucket value between 0 - 499, representing 50% of users. Group B users will be assigned a bucket value between 500 - 999, representing the other 50% of users. Group A users will experience Scenario 1 and Group B users experience Scenario 2. Scenario performance can be measured using Sourcepoint reporting to inform your strategy moving forward.

Controlled Rollouts

Partition sets can also be used to control the percentage of users being exposed to a new messaging experience. For example, if you would only like 10% of your users to experience a messaging scenario, you can create a partition set with a single partition and that partition is set up to only show to users with a bucket between 0 - 99.
