If the number of partitions is not enough, it can be changed and Dapr's sidecar will automatically redistribute the reminders's set.

### Enabling actor reminders partitioning
|
||||
Actor reminders partitioning is currently in preview, so enabling it is a two step process.
|
||||
|
||||
#### Preview feature configuration
|
||||
Before using reminders partitioning, actor type metadata must be enabled in Dapr. For more information on preview configurations, see [the full guide on opting into preview features in Dapr]({{< ref preview-features.md >}}). Below is an example of the configuration:
|
||||
|
||||
```yaml
|
||||
apiVersion: dapr.io/v1alpha1
|
||||
kind: Configuration
|
||||
metadata:
|
||||
name: myconfig
|
||||
spec:
|
||||
features:
|
||||
- name: Actor.TypeMetadata
|
||||
enabled: true
|
||||
```
|
||||
|
||||
#### Actor runtime configuration
|
||||
Once actor type metadata is enabled as an opt-in preview feature, the actor runtime must also provide the appropriate configuration to partition actor reminders. This is done by the actor's endpoint for `GET /dapr/config`, similar to other actor configuration elements.
|
||||
#### Actor runtime configuration for actor reminders partitioning
|
||||
First, the actor runtime must provide the appropriate configuration to partition actor reminders. This is done by the actor's endpoint for `GET /dapr/config`, similar to other actor configuration elements.

|
||||
|
||||
#### Handling configuration changes
|
||||
For production scenarios, there are some points to be considered before enabling this feature:
|
||||
|
||||
* Enabling actor type metadata can only be reverted if the number of partitions remains zero, otherwise the reminders' set will be reverted to an previous state.
|
||||
* Number of partitions can only be increased and not decreased. This allows Dapr to automatically redistribute the data on a rolling restart where one or more partition configurations might be active.
|
||||
To configure actor reminders partitioning, Dapr persists the actor type metadata in the actor's state store. This allows the configuration changes to be applied globally and not only in a single sidecar instance. Also the **number of partitions can only be increased and not decreased**. This allows Dapr to automatically redistribute the data on a rolling restart where one or more partition configurations might be active.
