Grouping Time Series for Efficient Columnar Storage
Summary: Groups time series by sharing a single time column to reduce timestamp repetition, at the expense of potential nulls. NP-hard to optimize; propose heuristic grouping, deployed in Apache IoTDB, with storage comparable to single-column schemes. (summarized by gpt-5-nano on Feb 09 2026)
