we have created streamtools – a new, open source project by The New York Times R&D Lab which provides a general purpose, graphical tool for dealing with streams of data. It provides a vocabulary of operations that can be connected together to create live data processing systems without the need for programming or complicated infrastructure. These systems are assembled using a visual interface that affords both immediate understanding and live manipulation of the system.via Aman
a Java based low latency, high throughput message bus, built on top of a memory mapped file; inspired by Java Chronicle with the main difference that it’s designed to efficiently support multiple writers – enabling use cases where the order of messages produced by multiple processes are important. MappedBus can be also described as an efficient IPC mechanism which enable several Java programs to communicate by exchanging messages.
