Query: Sprintz: Time Series Compression for the Internet of Things   Thanks to the rapid proliferation of connected devices, sensor-generated time
series constitute a large and growing portion of the world's data. Often, this
data is collected from distributed, resource-constrained devices and
centralized at one or more servers. A key challenge in this setup is reducing
the size of the transmitted data without sacrificing its quality. Lower quality
reduces the data's utility, but smaller size enables both reduced network and
storage costs at the servers and reduced power consumption in sensing devices.
A natural solution is to compress the data at the sensing devices.
Unfortunately, existing compression algorithms either violate the memory and
latency constraints common for these devices or, as we show experimentally,
perform poorly on sensor-generated time series.
  We introduce a time series compression algorithm that achieves
state-of-the-art compression ratios while requiring less than 1KB of memory and
adding virtually no latency. This method is suitable not only for low-power
devices collecting data, but also for servers storing and querying data; in the
latter context, it can decompress at over 3GB/s in a single thread, even faster
than many algorithms with much lower compression ratios. A key component of our
method is a high-speed forecasting algorithm that can be trained online and
significantly outperforms alternatives such as delta coding.
  Extensive experiments on datasets from many domains show that these results
hold not only for sensor data but also across a wide array of other time
series.
