DDlog is a programming language for incremental computation. It is well suited for writing programs that continuously update their output in response to input changes. A DDlog programmer does not write incremental algorithms; instead they specify the desired input-output mapping in a declarative manner. observed · 2026-08-28

DDlog is a programming language and compiler for incremental computation, based on a dialect of Datalog and differential dataflow. Programmers declare input-output mappings declaratively, and the compiler synthesizes efficient Rust implementations that continuously update outputs in response to streaming input changes.
Use cases
- maintain derived results incrementally as input relations change
- build real-time analytics over streaming relational updates
- implement static program analysis tools
- write declarative rules for cloud management systems
- compute all derived facts bottom-up from input relations
- process insert/delete/modify updates with minimal recomputation
When to choose
- your application continuously updates outputs in response to input changes
- you want declarative relational rules without writing incremental algorithms
- you need bottom-up computation of all derived facts
- you work with relational data streams and want amortized performance
When to avoid
- you need ad-hoc top-down queries rather than maintaining all derived facts
- your data does not fit in memory
- you need a general-purpose programming language rather than a declarative DSL
- you require active community maintenance - the repo is archived
