    Transforming Shape Schemas with Composable Property-Graph Queries (Extended Version)

    Philipp Seifer, Daniel Hernández, Ralf Lämmel, Steffen Staab

    cs.DB · cs.AI · cs.LO

    Property graphs may be constrained by schemas that inform both query engines and human users about the shape of valid data, enforcing a contract between data provider and consumer. Composable property-graph queries transform input graphs into output graphs. Then, the question arises of which schema can be expected after one (or several) transformation steps. We investigate how schema constraints can be inferred given an input schema and a...

    Vivace: Exact Temporal OLAP over Interval Histories via Independent Serverless Execution

    Woohyeok Park, Taeyoon Kim, Hyunjoon Kim, Kungyong Lee

    cs.DB · cs.DC

    Temporal online analytical processing (OLAP) analyzes past states of data whose values change over time. Such histories are naturally stored as interval histories, in which each row records the period during which a value remained valid. Because temporal analyses typically arrive in infrequent, intermittent bursts, serverless execution that launches functions only at query time offers a cost advantage over always-on clusters. Splitting a...
