From looking at the description it sounds more like subscriptions to events of data changes that are dispatched close to the data operation
How would realtime even work for a networked system going over tcp?
> A system is said to be real-time if the total correctness of an operation depends not only upon its logical correctness, but also upon the time in which it is performed. Real-time systems, as well as their deadlines, are classified by the consequence of missing a deadline:
> Hard – missing a deadline is a total system failure.
> Firm – infrequent deadline misses are tolerable, but may degrade the system's quality of service. The usefulness of a result is zero after its deadline.
> Soft – the usefulness of a result degrades after its deadline, thereby degrading the system's quality of service.
From what I can tell, https://pocketbase.io/ attempts to be a soft-realtime system.
