Bussig

Postgres Message Bus for .NET

• Queues, dead letter queues
• Manual or automatic queue name/topic creation
• Ability to delay re-processing of message when abandoning. Backoff setting.
• Topics/subscription and DL
• Possibly async fan out (one insert into topic outbox)
• Serialization support (System.Text.Json, Newtonsoft.Json, custom), (encrypt messages aes)
• Message versioning
• cron jobs/schedules, quartz/hangfire
• Polling: poll messages, poll health check. Option for using notify/listen?
• Request/reply
• Support for pgbouncer (transaction mode vs prepared statements)
• Inbox/outbox
• Tenants?
• OpenTelemetry
• Priority queueing
• Message deduplication maybe? Otherwise idempotent, or use sagas instead
• A processor/consume context alternative that returns a message, the framework handles the sending of it, with outbox if configured
  • For example: IConsumeMessage<TConsumeMessage>, IConsumeMessage<TConsumeMessage, TSendMessage>, IConsumeMessage<TConsumeMessage, IEnumerable<TSendMessage>>

public interface IConsumeMessage<TConsumeMessage> {
    public async Task Consume(TConsumeMessage message)
}
public interface IConsumeMessage<TConsumeMessage, TSendMessage> {
    public async Task<TSendMessage> Consume(TConsumeMessage message)
}
public interface IConsumeMessage<TConsumeMessage, IEnumerable<TSendMessage>> {
    public async Task<IEnumerable<TSendMessage>> Consume(TConsumeMessage message)
}

Post-MVP

• Awesome saga support, MassTransit-esque
• Attachment support (blobs, no storing of files in pg). Compression?
