Differential Dataflow for Datalog in Dynamic Settings
A new paper on arXiv (2308.04214v2) explores the efficiency of materialization in datalog engines, which are crucial for knowledge representation and reasoning in AI. Materialization, the evaluation of a datalog program and its incorporation into a database, becomes complex and resource-intensive when data is highly dynamic, as in distributed environments. Incremental materialization, which adjusts computation to new data rather than restarting, is standard, but handling deletions is more complicated than additions due to cascading effects. Differential Dataflow offers a computational model that ensures consistent performance for both additions and deletions. The paper evaluates three distinct datalog implementations, one based on a streamlined approach, to assess the suitability of Differential Dataflow for datalog interpretation in such settings.
