## Deduplication
VictoriaMetrics de-duplicates data points if `-dedup.minScrapeInterval` command-line flag
is set to positive duration. For example, `-dedup.minScrapeInterval=60s` would de-duplicate data points
on the same time series if they fall within the same discrete 60s bucket. The earliest data point will be kept. In the case of equal timestamps, an arbitrary data point will be kept. The `-dedup.minScrapeInterval=D` is equivalent to `-downsampling.period=0s:D` if [downsampling](#downsampling) is enabled.

The `-dedup.minScrapeInterval=D` is equivalent to `-downsampling.period=0s:D` if [downsampling](#downsampling) is enabled. It is safe to use deduplication and downsampling simultaneously.
The recommended value for `-dedup.minScrapeInterval` must equal to `scrape_interval` config from Prometheus configs. It is recommended to have a single `scrape_interval` across all the scrape targets. See [this article](https://www.robustperception.io/keep-it-simple-scrape_interval-id) for details.
