InfluxDB Cloud: points limit retention policy

[melanchall]

Proposal:
I suggest to provide new retention policy for buckets. Idea is to keep fixed number of last measurement points. So if new point is added and existing points count is equal to limit, oldest point from those existing points will be deleted.

Current behavior:
Currently we have two retention options: delete never and delete older than.

Use case:
In my opinion it will be useful for Free plan for those people who haven't large amounts of uploaded data and add a couple of measurement points per hour, for example.

Let's imagine, 1 point is added per day. With Free plan we currently can keep only 30 last points (since 30 days is maximum retention period). But with new option we can store, for example, last 1000 points and keep more data for our scenario.

I'm developer of an open-source library so I don't get any money for this work and want to use Free plan. My amounts of uploaded points is pretty small I suppose, so the new retention policy will be extremely useful.

@melanchall thanks for the issue. I think "size" for a retention policy makes sense and it's something we would like to add for sure.

Is there a reason you can't use the OSS Beta builds? Or you just don't want to run it yourself?

Hi, @russorat,

Yes, I want in-cloud solution to have relaibale way to store my metrics. With local computer I can't guarantee that :) I use Cloud for metrics of my open-source project.
