Amir and Jonathan - thanks for speaking up for the "more than 18 months" use cases. If dumps were *much* easier to use (via python clients that made it transparent whether you were hitting the API or not), would that be an acceptable solution? I feel like both of your use cases are not things that will be happening on a daily basis. If that's true, another solution would be an ad-hoc API that took in a filter and a date range, applied it server-side, and gave you a partial dump with only the interesting data. If this didn't happen very often, it would allow us to trade processing time and a bit of dev time for more expensive storage.Or, if we end up needing frequent access to old data, we should be able to justify spending more money on more servers. Just trying to save as much money as possible :)Thanks all so far, please feel free to keep chiming in if you have other use cases that haven't been covered, or if you'd like to add more weight behind the "more than 18 months" use cases.On Fri, Jul 29, 2016 at 3:18 PM, Leila Zia <leila@wikimedia.org> wrote:Dan, Thanks for reaching out.18 months is enough for my use cases as long as the dumps capture the exact data structure.Best,Leila

It makes sense to compare them not only to the previous week, but also to the same month previous year. So one year is not hardly enough. 18 months is better, and three years is much better because I'll be able to check also the same month in earlier years.
I imagine that this may be useful to all product managers that work on features that can affect traffic.

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 yearneed weekly resolution for 2 yearsneed monthly resolution for 3 yearsThank you!Dan
