Cortex.Streaming

Real-time DataFrame streaming engine with windowed aggregations for Cortex.

Part of the Cortex data science ecosystem for .NET.

Requires .NET 10+ and the Cortex core package.

Features

  • Micro-batch streaming — process real-time data as a stream of DataFrames
  • Windowed aggregations — tumbling, sliding, and session windows
  • Stateful processing — maintain running state across micro-batches
  • Pluggable sources and sinks — extensible connector architecture
  • Backpressure handling for reliable stream processing

Installation

dotnet add package Cortex.Streaming

Quick Start

using Cortex;
using Cortex.Streaming;

var stream = new DataFrameStream()
    .From(new CsvSource("events/*.csv", pollingInterval: TimeSpan.FromSeconds(5)))
    .Window(TumblingWindow.Of(TimeSpan.FromMinutes(1)))
    .GroupBy("sensor_id")
    .Agg(x => x.Mean("temperature"))
    .To(new ConsoleSink());

await stream.StartAsync();

Window Types

// Tumbling windows (non-overlapping)
.Window(TumblingWindow.Of(TimeSpan.FromMinutes(1)))

// Sliding windows (overlapping)
.Window(SlidingWindow.Of(size: TimeSpan.FromMinutes(5), slide: TimeSpan.FromMinutes(1)))

// Session windows (gap-based)
.Window(SessionWindow.WithGap(TimeSpan.FromMinutes(10)))
