Latest Patents

Zhihao Li holds a patent for "Direct cold tier upserts and partition splits enabling concurrent streaming data ingestion for time series databases." This patent describes techniques for performing a scratch space flush of cold tier upsert data into cold tier storage while allowing continued hot tier ingestion. The invention allows data points to be written directly into the cold tier, bypassing the hot tier, which typically stores new data points that are eventually aged out into the cold tier. This method enables new data points for insertion directly into the cold tier to be stored in scratch space storage and moved into the cold tier according to a non-blocking protocol. This innovation allows for continued hot tier ingestion without significant service disruptions.
