Wallaby

Postgres Change Data Capture for .NET, driven by your EF Core or Marten model.

Wallaby streams row changes from Postgres logical replication, materializes them into your mapped EF Core entities or Marten documents, lets you transform/enrich them, and routes the resulting documents to pluggable destinations (sinks). It self-configures the publication and replication slot from your model, supports backfill operations, and is cluster-safe via leader election.

Meilisearch and HTTP/webhook sinks are supported out of the box. Contributions for additional sinks is welcome.

Packages

Project Purpose
Wallaby Core package (provider-agnostic).
Wallaby.Providers.EntityFrameworkCore EF Core storage provider.
Wallaby.Providers.Marten Marten storage provider.
Wallaby.Sinks.Http HTTP/webhook destination sink.
Wallaby.Sinks.Meilisearch Meilisearch destination sink.

Quick start

builder.Services.AddDbContextFactory<AppDbContext>(o => o.UseNpgsql(conn));

builder.Services.AddWallaby(cdc =>
{
    cdc.UseEntityFrameworkCore<AppDbContext>()
       .UseConnectionString(conn)
       .ConfigureOptions(o => { o.SlotName = "app_cdc"; o.PublicationName = "app_cdc_pub"; })
       .AddMeilisearchSink("meili", m => { m.Host = "http://localhost:7700"; m.ApiKey = key; })

       // Mapping = routing only. The transform does the data shaping.
       .WithMappings(sink => sink
            .Map<Product>()
            .ToDestination("products")
            .WithBackfillVersion("v1")           // bump to force a reindex/backfill
            .UsingTransform((db, changes, ct) =>
            {
                var docs = new Dictionary<DocumentKey, WallabyDocument?>();
                foreach (var c in changes)
                    docs[c.Key] = new WallabyDocument { ["name"] = c.Entity!.Name };
                return Task.FromResult<IReadOnlyDictionary<DocumentKey, WallabyDocument?>>(docs);
            }));
});

Tests

The test suite requires docker to run and can be executed via .\build.ps1 Test

All test projects use TUnit; shared fixtures (e.g. the Postgres container) live in tests/Wallaby.TestInfrastructure.
