Configuring Storage Settings for Digital Event Services

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.
Storage Batch Size	Required. Defines the number of events that must be added to the on-disk store-and-forward queue before the queue is persisted to disk. 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. 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.
