What it is

RisingWave is a stream processing platform written primarily in Rust that unifies CDC ingestion, event stream processing, and real-time serving into a single system. It replaces traditional stacks (Debezium + Kafka + Flink + serving DB) by continuously ingesting data from PostgreSQL, MySQL, Kafka, S3, webhooks, and other sources, performing incremental computation, and serving fresh results at low latency for agentic AI and real-time applications. Monorepo structure: src/batch/ contains batch execution engine with modular executors in src/batch/executors/src/executor/ (hash_agg, hash_join, nested_loop_join, s3_file_scan, postgres_query, mysql_query, etc.), benchmarks in benches/…

Start here

Open these first:

• src/batch/src/lib.rs — Primary entry point for the batch execution module that orchestrates all executors and task management.
• src/batch/executors/src/executor.rs — Core executor trait and dispatcher defining the interface all batch operations must implement.
• src/batch/src/task/task_manager.rs — Task lifecycle management and coordination between distributed worker nodes.
• src/batch/src/execution/mod.rs — Execution engine abstraction handling both local and gRPC-based remote execution strategies.
• src/batch/src/rpc/service/task_service.rs — gRPC service layer defining remote task execution protocol and serialization contracts.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone: git clone https://github.com/risingwavelabs/risingwave.git. Install: verify Rust toolchain via rustup (primary language is Rust); examine workspace Cargo.toml for any pinned versions. Build batch module: `cd…

Daily commands:

For batch executors specifically: cd src/batch/executors && cargo build --release then run benchmarks with cargo bench. Full system initialization requires services beyond this module; verify environment setup in ma…

Key cautions & unknowns

• Workspace dependencies: many crates (risingwave_common, risingwave_connector, risingwave_storage, risingwave_rpc_client, risingwave_pb) are pulled from workspace configuration not shown in provided data; building…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
