TimeUnion: An Efficient Architecture with Unified Data Model for Timeseries Management Systems on Hybrid Cloud Storage

Summary: TimeUnion proposes a unified data model for independent and grouped timeseries on hybrid cloud storage. It uses memory-efficient structures and a time-partitioned LSM-tree with tailored compaction and out-of-order handling, delivering 5x more series, 24.8% higher insertion throughput, and 49.8% lower latency than Cortex; open-source.
