That's very useful, Alex, thanks!  I guess those requests would need to be covered by dumps anyway, since we only have data back to 2015.  I'll ping Henrik too.

Maybe it make sense to ask Henrik (stats.grok.se) for his download stats. 

We at wikipediatrends.com usually receive < 5 request/month for full data (from 2008).

Dear Pageview API consumers,

We would like to plan storage capacity for our pageview API cluster.  Right now, with a reliable RAID setup, we can keep 18 months of data.  If you'd like to query further back than that, you can download dump files (which we'll make easier to use with python utilities).

What do you think?  Will you need more than 18 months of data?  If so, we need to add more nodes when we get to that point, and that costs money, so we want to check if there is a real need for it.

Another option is to start degrading the resolution for older data (only keep weekly or monthly for data older than 1 year for example).  If you need more than 18 months, we'd love to hear your use case and something in the form of:

need daily resolution for 1 year

need weekly resolution for 2 years

need monthly resolution for 3 years

Thank you!

Dan
