In our previous Introduction to the Any Type blog, we learned about the new EPL any type introduced in 10.1. In 10.2, we expanded the set of reflection capabilities on the any type. These new additions increase our ability to write even more generic and dynamic Apama applications, so let’s explore them now! Reflection Capabilities Of the Any Type:
Reflection allows EPL to act on values of an any type object in a generic way, including altering the behavior to adapt to what fields or actions a type has.… Read More
In Apama 10.2 we have upgraded the versions of Docker that we use. We have moved to Docker v17.09.0-ce, Docker Compose v1.16.1 and Compose API 3.3. In addition we have also introduced support for using Kubernetes. Our Docker samples now include Kubernetes orchestration files that are the equivalent of the the YAML files supplied for Docker Compose. Assumed KnowledgeHow to start a correlator, including using a YAML configuration.

Apama image and application samples are now available as a ready-to-go Docker image along with Kubernetes config file on GitHub! Please visit https://github.com/SoftwareAG/apama-streaming-analytics-docker-samples to get started.
These samples function using the provided Dockerfile to create an image from your Apama installation. Most of them also work with the pre-built images, which are available for free from Docker Store. You can add them to your Store account by visiting https://hub.docker.com/_/apama-correlator.
The GitHub repository contains configuration and samples to help you containerize and run Apama components and applications in Docker.… Read More
The latest version of Apama Community Edition has arrived bringing enhanced connectivity options and usability improvements for Apama EPL.… Read More
In Apama 10.1, we introduced a new type any to EPL, which can hold a value of any concrete EPL type (equivalent to Object type in Java or auto in C++). This means it is now possible to write EPL applications in much more generic ways. In this blog, we shall explore some of new possibilities, code simplifications and other benefits that the any type gives us. To get the full story on how any functions (what actions are available on it and similar) please refer to the samples or doc.… Read More
Last week, SoftwareAG held a cross-company innovation event, where engineers from across the globe came together to create cool new systems and technologies. For one team in Apama, that of course meant playing around with RaspberryPi devices. Community members might recall our previous internal hackathon which produced an EPL plug-in for interfacing Apama with the on board GPIO system, and we are happy to report that this project has made a lot of progress in the past few days.… Read More
