Research direction

Start by locating IOutboxStore and the batch dispatch code, then read the PostgreSQL and SQL Server store implementations. Implement safe concurrent claiming with PostgreSQL FOR UPDATE SKIP LOCKED and SQL Server UPDLOCK with READPAST behind the interface; done means two dispatchers cannot send the same row at the same time.

Written by the indexing model from the issue text.

Description

area: dispatch enhancement

Two dispatchers must never send the same row at the same time. PostgreSQL gets FOR UPDATE SKIP LOCKED, SQL Server gets UPDLOCK with READPAST, both behind IOutboxStore.
