PhilipDaubmeier.CompactTimeSeries 1.2.0

CompactTimeSeries

CompactTimeSeries is an in-memory time series library for space-efficient storing, processing, resampling and compressing of time series data.

NuGet

PM> Install-Package PhilipDaubmeier.CompactTimeSeries

When should I use it?

If you need to deal with mostly equidistant time series with a large number of values, e.g. sensor readings that are equally spaced in time, and need to process them in memory. The main classes of this library, which implement ITimeSeries<T> allow for convenient random access read/write to a time series via time-based indexers.

If you need fast persisting/loading of such time series data, this library will not help you - just use a time series database like Influx, Graphite, CrateDB etc.

Usage

// Create a time series for today with 1 second spacing, which will result in 86400 values
var span = new TimeSeriesSpan(DateTime.Now.Date, DateTime.Now.Date.AddDays(1), TimeSeriesSpan.Spacing.Spacing1Sec);
var timeseries = new TimeSeriesStream<int>(span);

// Write to the time series via time-based indexer: the time bucket for the current second will be written
timeseries[DateTime.Now] = 42;

// Enumerate the time series values and timestamps like an IEnumerable<KeyValuePair<DateTime, T?>>
foreach (var timestampedValue in timeseries)
    DoSomething(timestampedValue);

For more usage examples you can also have a look at the unit tests.

Platform Support

CompactTimeSeries is compiled for .NET Core 2.2.
