Wallaroo is an efficient, low-footprint, event-by-event data processing engine with on-demand scaling. Wallaroo falls into the ââ¬Åstream processingââ¬Â category along with tools like Apache Storm, Apache Flink, and Apache Spark Streaming. Wallaroo can deliver performance and cost efficiencies that the other tools canââ¬â¢t meet ââ¬â whether deployed on-premise, in any cloud, or at the edge. We built Wallaroo because accurately and quickly processing large streams of data is very hard. It requires the practical application of deep academic work in distributed computing, complex testing, and more. Wallaroo simplifies the launching of high-throughput, low-latency applications, even when the correctness of results and resiliency are critical (known as effectively-once or exactly-once processing). Itââ¬â¢s designed to work with multiple sources and consumers of data: Kafka, AWS Kinesis, HTTP, MySQL, HDF
