Abstract: Techniques for performing a scratch space flush of cold tier upsert data into cold tier storage while allowing continued hot tier ingestion are described. Data points to be written into a time series database having a hot tier and a cold tier may be designated to be written directly into the cold tier, bypassing the hot tier that typically stores new data points that eventually are aged out into the cold tier. New data points for insertion directly into the cold tier may be stored to a scratch space storage and moved into the cold tier according to a non-blocking protocol that allows for continued hot tier ingestion without significant service disruptions.
