NOSQL/SQL Embedded Data Management for Edge Applications

Actian

A Helm chart for Actian Zen DB optimized for OpenNESS 20.09

Overview of Actian Zen DB

Actian Zen Edge Data Management is a single, secure, modular, and scalable solution that embeds in or bundles with applications for remote/branch, mobile, and IoT data processing and analytics support. Zen provides SQL and NoSQL access for any type of data from within most popular programming languages on Windows (IoT Core, Desktop, Server), Linux (embedded and standard), MacOS running on Intel platforms and running on iOS/Android for mobile.

Prerequisites

Predeployed container images from https://github.com/ActianCorp/ActianZen-OpenNESS on edge nodes:

actianzen-openness20.09.tar.gz: The docker container image for the Actian Zen Server
zensample-openness20.09.tar.gz: The docker container for the Zen client and sample application

Images can be predeployed on edge nodes by copying them to the respective hosts and loading them in Docker these commands:

docker image load -i actianzen-openness20.09.tar.gz
docker image load -i zensample-openness20.09.tar.gz

The Helm charts for deploying these images are located under the “charts” and should be copied to the controller for deployment.

It is recommended that a namespace is created (such as “zen”) for deploying Actian Zen container and associated container applications.
