Stream data processing is becoming increasingly important to support business needs for faster time to insight and action with growing volume of information from more sources. Apache Apex (http://apex.apache.org/) is a unified big data in motion processing platform for the Apache Hadoop ecosystem. Apex supports demanding use cases with:
* Architecture for high throughput, low latency and exactly-once processing semantics.
* Comprehensive library of building blocks including connectors for Kafka, Files, Cassandra, HBase and many more
* Java based with unobtrusive API to build real-time and batch applications and implement custom business logic.
* Advanced engine features for auto-scaling, dynamic changes, compute locality.
Apex was developed since 2012 and is used in production in various industries like online advertising, Internet of Things (IoT) and financial services.
