-csvTrimTimestamp duration
Trim timestamps when importing csv data to this duration. Minimum practical duration is 1ms. Higher duration (i.e. 1s) may be used for reducing disk space usage for timestamp data (default 1ms)
-dedup.minScrapeInterval duration
Remove superflouos samples from time series if they are located closer to each other than this duration. This may be useful for reducing overhead when multiple identically configured Prometheus instances write data to the same VictoriaMetrics. Deduplication is disabled if the -dedup.minScrapeInterval is 0
