Downsampling data #36
VictoriaMetrics doesn't provide automatic downsampling at the moment. But it may be implemented using the following approach:
We are planning to add recording rules to VictoriaMetrics with the ability to export the recorded data into external storage such as another VictoriaMetrics instance with higher retention.
Downsampling is usually used for two purposes:
VictoriaMetrics is optimized for both cases
So VictoriaMetrics work quite good without the downsampling. An additional benefit is that you can drill down old data to small time ranges without precision loss.
I'm commenting part as a +1 on this being a requested feature, and part answering questions posted on reddit by @valyala about reasons to use VM.
To be able to downsample data like RRD in combination with the current storageefficiency of large amounts of timeseries, and being able to query this downsampled data transparently is imho. the featureset required for VM to become the obvious choice for devops/dashboards.
