Alltime Statistics

[Karen K]

I just read a post about slow skin creation in a german weather forum. This made me think about something. There were threads about the same topic here.

Sometime the DaySummaryManager was introduced. And I guess the reason was to speed up aggregations. Instead of 288 records a day one record had to be read only. This can make the difference for large databases.

Now if I think of a database of 10, 20 or more years. And I want to see some alltime statistics. Even the day summary table is large in those cases. 

So I wonder if it would help to have a year summary table, too.

I've been thinking of that too, although with a monthly summary. It would add a lot of code and a lot of complexity. I don't think we're quite there yet.

Sure. That's the easy part.

We're talking about optimizing the calculation by using monthly or yearly summaries, which is much more difficult.

I had once had the alltime stats computed and populated in table. Similar to https://github.com/glennmckechnie/alltimeSeasons/tree/master/weewx491 but using xtypes instead. Unfortunately i didnt have it backed up and a sd card crash lost everything for me :(
