When you are working with continuous aggregates, you can drop a view, or you can drop raw data from the underlying hypertable or from the continuous aggregate itself. A combination of [refresh][cagg-refresh] and data retention policies can help you downsample your data. This lets you keep historical data at a lower granularity than recent data.
However, you should be aware if a retention policy is likely to drop raw data from your hypertable that you need in your continuous aggregate.
To simplify the process of setting up downsampling, you can use the [visualizer and code generator][visualizer].
