The Role of Semirings in Incremental View Maintenance
Eden Chmielewski, Andrei Draghici, Dan Olteanu +1
We study the problem of incremental view maintenance (IVM) under inserts to semiring-annotated databases. The key observation put forward in this paper is that the complexity of th…

Recent Increments in Incremental View Maintenance
Dan Olteanu
We overview recent progress on the longstanding problem of incremental view maintenance (IVM), with a focus on the fine-grained complexity and optimality of IVM for classes of conj…
