Are you expecting a real answer of how I was hoping timescale's internal watermark system would help me roll up a total count or are you just implying I'm an idiot?
- mardifoufs 3y agoWhat's the difference between the watermark and a time column? Not the person you were replying to but I'm curious since I also thought that TimeseriesDB had a similar "timestamp" to influx.
- efxhoy 3y agoTS requires you to specify a time column in each hypertable or view (continuous aggregate) where you want it to work its magic. It then stores an internal watermark that it compares to the time column in the table to figure out from where to read when refreshing. My issue was that for a grand total I didn’t have a time column, so I couldn’t define my query as a continuous aggregate and the query had to start counting from the start of my underlying series each time.
- pbronez 3y agoPerhaps: add a time column with an artificially huge time range? This defines the grand total as an interval sum that happens to include all possible intervals.
