>_STRYKE-KAFKA
Streams without the JVM. Apache Kafka client for stryke — producer, consumer, admin, and consumer-group lag. Opt-in package backed by rdkafka (librdkafka bindings).
Install
# build the helper binary, install as a stryke package cd ~/projects/stryke-kafka cargo build --release s pkg install -g . # one-liner make install # verify kafka --help
After install, kafka --help works from anywhere on PATH (assuming ~/.stryke/bin/ is on PATH). The stryke library is auto-discoverable to any project that depends on the package via [deps] kafka = { path = "..." } or, when published, by name.
CLI: kafka
| produce a message | kafka produce my-topic 'hello world' |
| consume from earliest | kafka consume my-topic --from-beginning --json |
| list topics | kafka topics list |
| create a topic | kafka topics create new-topic --partitions 12 --replication 3 |
| consumer-group lag | kafka lag my-group |
| describe brokers | kafka brokers describe |
The full flag matrix lives in the README "CLI" section.
Why a package, not a builtin
librdkafka is the canonical native Kafka client. Bundled here as an opt-in stryke package so workflows that need it don't bloat the core binary.
The stryke side is a thin NDJSON-pipe wrapper; the heavy code lives in the stryke-kafka-helper sidecar binary and is loaded on demand. Core stryke is never linked against this package's deps.
Helper protocol
The stryke-kafka-helper sidecar speaks newline-delimited JSON over stdin/stdout. The stryke library shells out per call and pipes structured data both ways. This keeps stryke startup small while making the package's surface area available on demand.
# manual invocation (debugging only)
