WebThis thesis examines compression algorithms for time series operational data which are collected from the Controller Area Network (CAN) bus in an automotive Internet of Things (IoT) setting. The purpose of a compression algorithm is to decrease the size of a set of time series data (such as vehicle speed, wheel speed, etc.) so that the data to be WebData compression for process historians involves reducing the number of data points that are stored, while trying to not affect the quality of the data. Compression can be accomplished using one of several algorithms (swinging door, Box Car Back Slope). Each algorithm uses some criteria to eliminate data between points where there is constant ...

WebAug 31, 2016 · At the same compression ratio, it compresses substantially faster: ~3-5x. At the same compression speed, it is substantially smaller: 10-15 percent smaller. It is almost 2x faster at decompression, regardless of compression ratio; the command line tooling numbers show an even bigger difference: more than 3x faster.
WebMay 20, 2024 · These techniques give better compression ratio for VictoriaMetrics comparing to competitors — it compresses typical node_exporter time series data to 0.4 bytes per data point. This is 10x times better than 4 bytes per data point for the same data in Prometheus, which uses the original Gorilla compression algorithm. grand library menaphosWebRun-length encoding (RLE) is a form of lossless data compression in which runs of data (sequences in which the same data value occurs in many consecutive data elements) are stored as a single data value and count, rather than as the original run. This is most efficient on data that contains many such runs, for example, simple graphic images such as icons, … chinese food in roxboro ncWebJan 7, 2024 · The data redundancy will be reduced greatly using Delta encoding especially when the differences between the data in the time series is slight.
