Perupdate

Perupdate is a neologism used in computing to refer to a mechanism, policy, or mode of operation that treats updates on a per-event basis rather than in bulk. Because it is not a standard term, its exact meaning varies by context.

In software deployment and data synchronization, perupdate may describe a model that applies each update to a target immediately after it is produced, rather than aggregating changes into a single batch. It can also refer to notifications delivered for every update.

In database replication or collaborative editing, perupdate can describe propagating individual transactions or changes as separate messages. This approach can reduce latency and simplify conflict resolution, but it often increases communication overhead and places higher demands on ordering and fault tolerance.

Implementation considerations include maintaining idempotence, preserving transaction boundaries, ensuring correct event ordering, handling partial failures, and evaluating network and storage costs. The choice between perupdate and batch updates involves a trade-off between immediacy and efficiency.

Example: a mobile data collection app that pushes each new record to the server as soon as it is created. Perupdate improves responsiveness but may exhaust bandwidth on low-signal networks. Critics argue for hybrid approaches that batch updates under high latency conditions.
