Oproto.FluentDynamoDb.Streams

DynamoDB Streams processing support for Oproto.FluentDynamoDb, enabling fluent event handling in AWS Lambda functions.

Installation

dotnet add package Oproto.FluentDynamoDb.Streams

Overview

This package provides a fluent API for processing DynamoDB stream events in AWS Lambda functions. It integrates seamlessly with the Oproto.FluentDynamoDb source generator for type-safe entity deserialization.

Usage

using Oproto.FluentDynamoDb.Streams;
using Amazon.Lambda.DynamoDBEvents;

public class StreamHandler
{
    public async Task HandleAsync(DynamoDBEvent dynamoEvent)
    {
        var processor = new StreamProcessor<Order>();
        
        await processor
            .OnInsert(async order => 
            {
                Console.WriteLine($"New order: {order.OrderId}");
            })
            .OnModify(async (oldOrder, newOrder) => 
            {
                Console.WriteLine($"Order updated: {newOrder.OrderId}");
            })
            .OnRemove(async order => 
            {
                Console.WriteLine($"Order deleted: {order.OrderId}");
            })
            .ProcessAsync(dynamoEvent);
    }
}

Features

  • Type-Safe Deserialization: Automatic entity mapping using source-generated code
  • LINQ-Style Filtering: Filter events before processing
  • Discriminator Routing: Route events to handlers based on entity type in single-table designs
  • AOT Compatible: Full support for Native AOT compilation
  • Fluent API: Chain handlers for clean, readable code

Single-Table Design Support

// Route events based on entity discriminator
var processor = new MultiEntityStreamProcessor()
    .ForEntity<Order>(p => p
        .OnInsert(async order => { /* handle new order */ })
        .OnModify(async (old, @new) => { /* handle order update */ }))
    .ForEntity<Customer>(p => p
        .OnInsert(async customer => { /* handle new customer */ }));

await processor.ProcessAsync(dynamoEvent);
