A Rust library implementing differential dataflow on top of timely dataflow, enabling data-parallel programs that efficiently process large data collections and rapidly respond to arbitrary input changes. Programs are written as functional transformations (map, filter, join, reduce, iterate) that incrementally update outputs as inputs change.
Use cases
- incrementally update query results as input data changes
- compute graph analytics like reachability on dynamically changing graphs
- process large streaming datasets with low-latency updates
- build data-parallel pipelines with joins and iterative computations
- implement real-time analytics that respond to arbitrary collection changes
When to avoid
- you only need simple batch processing without incremental updates
- you prefer higher-level SQL or streaming engines over low-level dataflow programming
- your team is not comfortable with Rust and functional dataflow semantics
