DotNetWorkQueue.Transport.PostgreSQL

PostgreSQL transport for DotNetWorkQueue.

Features

  • PostgreSQL message storage using Npgsql
  • Supports delayed processing, message expiration, and priority queues
  • Heartbeat monitoring for long-running messages
  • Automatic table creation and schema management
  • Job scheduling with deduplication
  • Targets .NET 10.0, .NET 8.0, .NET Framework 4.8, .NET Standard 2.0

Installation

dotnet add package DotNetWorkQueue.Transport.PostgreSQL

Quick Start

// Producer
using var queueContainer = new QueueContainer<PostgreSqlMessageQueueInit>();
using var producer = queueContainer.CreateProducer<MyMessage>(
    new QueueConnection("queueName", "Host=localhost;Database=MyDb;Username=user;Password=pass;"));
producer.Send(new MyMessage { Text = "Hello" });

// Consumer
using var consumer = queueContainer.CreateConsumer(
    new QueueConnection("queueName", "Host=localhost;Database=MyDb;Username=user;Password=pass;"));
consumer.Start<MyMessage>(HandleMessage);

Performance tuning

Npgsql automatic statement preparation

Off by default in Npgsql, and this transport does not turn it on. The send path issues the same handful of statements repeatedly, which is the shape automatic preparation targets, so enabling it is worth considering — it is a connection-string change, not a code one:

Host=localhost;Database=MyDb;Username=user;Password=pass;Max Auto Prepare=20;Auto Prepare Min Usages=2;

Measured on this transport (net10, LAN PostgreSQL, 256-byte payload), across two runs:

operation effect
single send no measurable difference
batch of 100 13-17% faster

Allocation is unchanged. The benefit is on the batch path and only there — a single send showed a 6% gain in one run and none in another, which is noise rather than a small win. If you send one message at a time, this setting is not for you.

Before enabling it, know the trade-off. Prepared statements live on the physical connection and the pool hands that connection back out, so dropping or recreating a table invalidates any prepared statement referencing it. This library creates and drops queues as a normal operation, so that is not a hypothetical. A create/drop/recreate cycle is covered by an integration test (AutoPrepareSurvivesDdl) and does not fail — but Npgsql exposes no public counter for auto-prepared statements, so that test shows the scenario working rather than proving the invalidation path was exercised.

If your application creates and drops queues at runtime, measure your own workload before turning this on. If your queues are long-lived and you send in batches, it is close to free.
