Message Ordering
In plain terms
Ensuring messages are processed in the order sent.
Going deeper
Message ordering guarantees consumers see messages in a defined sequence, important when order matters for correctness. Some systems preserve it, others don't.
Under the hood
Partitioning preserves order within a partition (Kafka) but not globally; trade-off with parallelism.
Examples
Kafka partitions, event sourcing, sequential processing, FIFO queues.
Think of it like...
Like ensuring bank transactions apply in the order they occurred, not jumbled.
