Updating Instance
The permitted Time to Live limit for a Data Store is only 30 days (maximum). If it goes above that, data will not be there in the Story. Hence, the user can manually update the instance. The Days Left column will highlight such condition as flashing Expire status in the red color. Click the user gets redirected to update the instance for the selected Data Store so the data will be refreshed again in the ES or MongoDB.
Navigate to the Create New Story page.
Select a Data Store from the Personalised category that has been expired.
Click on the Data Store.
The Time to Live (TTL) option appears.
Mention no. of days (up to 30 days is allowed for TTL)
Click the Refresh option.
A notification message appears.
The Data Store gets refreshed, and the inserted no. of days get reflected under the Days Left column.
Please Note: The user can distinguish between Datastores:
