Camel: Efficient Compression of Floating-Point Time Series
Summary: Camel compresses floating-point time series by separating integer and fractional parts and selecting values that maximize compression, rather than XORing with the previous point. It also provides an index over compressed data for efficient querying and, across 22 public and 3 AliCloud industrial datasets, outperforms 11 lossless and 6 lossy baselines in compression ratio and efficiency.
