Dear Community, The Apache Apex community is pleased to announce release 3.7.0 of Apex Core (the engine).
Apache Apex is an enterprise-grade big data-in-motion platform that unifies stream and batch processing. Apex was built for scalability and low-latency processing, high availability and operability. This release adds the support for grouping engine events by the root cause, ability to specify custom log appenders, SSL improvements, back pressure improvements and a number of important bug fixes and improvements. See full release notes <https://s.apache.org/fWT8> for all changes in this release. Apex provides features that similar platforms currently don’t offer, such as fine-grained, incremental recovery to only reset the portion of a topology that is affected by a failure, support for elastic scaling based on the ability to acquire (and release) resources as needed as well as the ability to alter topology and operator properties on running applications. Apex early on brought the combination of high throughput, low latency and fault tolerance with strong processing guarantees to the stream data processing space and gained maturity through important production use cases at several organizations. See the powered by page and resources on the project website for more information: http://apex.apache.org/powered-by-apex.html http://apex.apache.org/docs.html The Apex engine is supplemented by Malhar, the library of pre-built operators, including adapters that integrate with many existing technologies as sources and destinations, like message buses, databases, files or social media feeds. An easy way to get started with Apex is to pick one of the examples as the starting point. They cover many common and recurring tasks, such as data consumption from different sources, output to various sinks, partitioning and fault tolerance: https://github.com/apache/apex-malhar/tree/master/examples/ <https://github.com/apache/apex-malhar/tree/master/examples/> Apex Malhar and Core (the engine) are separate repositories and releases. We expect more frequent releases of Malhar to roll out new connectors and other operators based on a stable engine API. The latest Malhar release 3.8. 0 works on existing Apex Core 3.6.0. The source release can be found at: http://apex.apache.org/downloads.html We welcome your help and feedback.
