Streaming Synchronous Recursion And Incremental Computation Incremental computation has traditionally had an uneasy relationship with recursion iteration. it turns out that the right operators for synchronous streaming provide a framework that elegantly supports both. Explore synchronous streaming operators for elegant support of recursion and incremental computation in databases. learn about algebraic equivalences and their analogy to discrete signal processing.
Lecture 2 Asynchrnous And Synchronous Computation Communication Pdf This lecture presents an algebra of concurrent streaming operators that can serve as a compilation target for rich query languages on collections (the db in dbsp). Stream processing defines a pipeline of operators that transform, combine, or reduce (even to a single scalar) large amounts of data. characteristically, data is accessed strictly linearly rather than randomly and repeatedly and processed uniformly. (databricks) structured streaming adopts the definitions of event time, processing time, watermarks and triggers from dataflow but incorporates them in an incremental model. We have been talking about general computation, but so far our language was very limited. we only used function calls, numbers, and simple variable binding. we will slowly add more language primitives and see how to still have full incrementality of the computation.

We give a high level overview of works on incremental computation, and highlight the essence underlying all of them, which we call incrementalization the discrete counterpart of differentiation in calculus. This approach contrasts with earlier approaches that aimed to incrementally evaluate non incremental programs. in essence, every program computes by fixed point iteration, expressed as recursive functions or loops. In this paper, we lay an analytical foundation for condi tions to check if a recursive aggregate program that is mono tonic or even non monotonic can be executed incrementally and asynchronously with its correct result. We want to calculate the new output in a way that performs better (lower latency, higher throughput, lower resource usage etc) than just repeatedly running the function from scratch.
