> when storing time series keys, you can save a lot of space by encoding them as a first timestamp followed by timestamp offsets (deltas)
It's actually a delta of deltas, which means for regular time series that a huge portion of rows will contain a 0 (more than 96% according to the paper) because all events arrive at a fixed interval; if there's a slight delay in either direction, the stored value will be small in most cases.
