Automatically remove data from continuous views
As an engineer using PI View or SQL writers for a report, I would like option to remove data older than a certain cutoff. For example, a continuous view is used to generate data for a report on the last 8 hours. Data older than that are no longer needed for the report and should be removed to avoid unnecessarily large tables.
One workaround with Text and Hadoop writers is the Append Timestamp option, but there's no ability to remove data from other targets.

I agree with this use case. For SQL targets, you could create a stored procedure to delete data older than a certain time, and then you can run it with SQL Agent. Not the most ideal scenario, but it works. Stack Overflow has a good example for deleting data here: https://stackoverflow.com/questions/1588722/delete-items-older-than-a-day-sql-server
