| Description |
|
The current implementation of the Prometheus functions doesn't allow NaN filtering. And the result of aggregation functions working with NaN always gives NaN as a result. This logic should be changed to ignore NaN values in the data set. |

We need to agree what to do if all values are ignored. "avg", "min", "max" aggregate functions FAIL with error "not enough data" (we propose to modify error message to "no data (at least one value is required)". "count" returns 0. The problematic one is "sum". It returns 0 in case no data values. We propose to modify "sum" to behave like "avg", "min", "max" - to FAIL with error "no data (at least one value is required)"). But there might be other opinions. |
