Feature Request: In-Memory Outbox for Deferred Message Publishing

Description:
This feature proposes implementing a lean and fast in-memory outbox mechanism to defer message publishing until the completion of a unit of work (e.g., an HTTP request or message consumer operation).

Key Features:

• Messages generated during a unit of work would only be published after the unit successfully completes (e.g., after Entity Framework SaveChanges()).
• The design would ensure a lightweight and performant solution suitable for high-throughput scenarios.

Customization Points:

1. Configurable Triggers:

   • Allow customization of the trigger that releases deferred messages (e.g., EF DbContext SaveChanges() or other specified events).

2. Selective Application:

   • Provide options to configure which transports and messages are subject to this deferred behavior.

Use Case:
This would enhance reliability and consistency in scenarios where message publishing depends on the successful completion of related operations, reducing the risk of partial or inconsistent outcomes.
