Configuring Storage Settings
Depending on the delivery mode that you configure for an event type, events sent to Digital Event Services (DES) are stored on-disk or in-memory. Use the following procedure to configure storage settings for DES.
Note: Depending on the runtime in which DES is embedded, events are emitted synchronously or asynchronously. When events are emitted synchronously, DES ignores the Sync Batch Size and Sync Timeout settings.
* To configure the storage settings for DES
1. In Command Central, navigate to Environments > Instances > All > instance_name > Digital Event Services > Configuration.
2. Select Runtime Configuration from the drop-down menu.
3. In the Name column, select Runtime Configuration, and then click Edit.
4. Specify values for each Field in the table as outlined in the Description column:
Field
Description
Storage Location
Optional. Defines the location where events are stored on-disk. Specify an existing folder in your file system.
Important: Before you specify a new storage location, if the existing storage location is in use, you must copy any existing files manually to the new storage location.
If you do not specify a value, events are stored in the same directory as the configuration.
You must restart the runtime where the DES component is embedded for the changes to the Storage Location property to take effect.
Sync Batch Size
Required. Defines the number of events that are added to the store-and-forward queue before the queue is persisted to disk. DES ignores the Sync Batch Size setting if events are sent synchronously.
The default value is 100 events.
Sync Timeout
Required. Defines the timeout in milliseconds that the on-disk store-and-forward queue waits before the events in the queue are persisted, in case the batch size has not been reached. DES ignores the Sync Timeout setting if events are sent synchronously.
The default value is 500 milliseconds.
Default On-Disk Capacity
Required. Defines the maximum number of events of each event type that can be stored on disk. The default value is 1000000.
Note: You can override the setting by specifying On-Disk Capacity per event type.
Default In-Memory Capacity
Required. Defines the maximum number of events of each event type that can be stored in the memory. The default value is 1000.
Note: You can override the setting by specifying In-Memory Capacity per event type.
5. Save your changes.
