Aliaksandr Valialkin	5b47c00910	app/vmselect/promql: use linear regression in deriv func like Prometheus does ... Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/73	2019-06-21 22:59:46 +03:00
Aliaksandr Valialkin	9e1119dab8	app/vmselect/promql: ajdust data model to the model used in Prometheus ... Do not take into account data points on the range `[timestamp .. timestamp+step)` when calculating value on the given `timestamp`. Use only data points from the past when performing these calculations like Prometheus does. This should reduce discrepancies between results returned by VictoriaMetrics and results returned by Prometheus.
