Exactly once delivery is theoretically impossible.
Approaching exactly once delivery asymptotically is possible. Your parent poster's point is that this is one where you can get so close to exactly once in order that in practice you never violate for years and years.
- rusanu 9y agoMy point is that I've seen people making decisions to go with 'best effort delivery' and live with the (costly) consequences because they read here and there that EOIO is impossible, so why bother trying.
- inlined 9y agoBecause idempotentcy can be cheap at the application layer, so why try to solve something we know can never truly be solved?
