Liftbridge

Lightweight, fault-tolerant message streams. Extend NATS with a Kafka-like durable pub/sub log API. Use Liftbridge as a simpler and lighter alternative to systems like Kafka and Pulsar or to add streaming semantics to an existing NATS deployment. Stream replication provides high availability and durability of messages. Clustering and partitioning provide horizontal scalability for streams and their consumers. No heavy or unwieldy dependencies like ZooKeeper or the JVM. Liftbridge is a single static binary roughly 16MB in size. It has a simple gRPC-based API which makes it quick to implement client libraries. Create streams that match wildcard topics, such as stock.nyse. or stock.nasdaq. in addition to topic literals like stock.nasdaq.msft. Messages can have a key set on them for key-value semantics and other arbitrary headers, making Liftbridge a great choice for transaction write-ahead logs.
