Nussknacker

Real-time actions on data. A building block for low-code real-time applications with event streaming and request-response capabilities. Nussknacker is a low-code visual tool for domain experts to define and run real-time decisioning algorithms instead of implementing them in the code. It serves where real-time actions on data have to be made: real-time marketing, fraud detection, Internet of Things, Customer 360, and Machine Learning inferring. An essential part of Nussknacker is a visual design tool for decision algorithms. It allows not-so-technical users – analysts or business people – to define decision logic in an imperative, easy-to-follow, and understandable way. Once authored, with a click of a button, scenarios are deployed for execution. And can be changed and redeployed anytime there’s a need. Nussknacker supports two processing modes: streaming and request-response. In streaming mode, it uses Kafka as its primary interface. It supports both stateful and stateless processing.

Streamvisor

Streamvisor is a web-based management and observability platform designed specifically for Apache Pulsar, aiming to simplify the complexities associated with managing and monitoring Pulsar clusters. By providing a comprehensive suite of tools, Streamvisor enhances visibility, operational efficiency, and security, enabling organizations to focus on delivering business value without being overwhelmed by the intricacies of their streaming infrastructure. One of the core features of Streamvisor is its observability capabilities. Users can gain deep insights into their event-driven architectures without requiring extensive Pulsar knowledge. The platform allows for real-time message viewing and filtering, facilitating quick identification and troubleshooting of issues. Additionally, the one-click message replay feature enables users to resend messages effortlessly, which is particularly useful for debugging and testing purposes. Streamvisor also supports access to multiple Pulsar environments, providing a unified interface for managing diverse deployments. In terms of management, Streamvisor accelerates application deployment by offering a scalable and structured Pulsar environment. Users can manage resources efficiently, enforce schemas to maintain data consistency, and quickly unload topics to rebalance load or resolve temporary issues. The platform also provides tools to troubleshoot consumers and producers, ensuring smooth operation of the messaging system. Security is a paramount concern addressed by Streamvisor through the implementation of granular access controls. The platform offers role-based access control (RBAC) at the resource level, allowing administrators to define fine-grained permissions for users and groups. Integration with authentication providers enables single sign-on (SSO), streamlining user authentication processes. External group mapping and service accounts further enhance security by providing flexible and secure access management. Additionally, Streamvisor includes a data catalog for documenting streams and an audit log to trace user actions, ensuring compliance and accountability. Streamvisor is designed for ease of installation and integration. It can be deployed using Docker Compose or Helm charts, allowing for quick setup in various environments. The platform seamlessly integrates into existing architectures without requiring changes to Pulsar, ensuring that all data remains within the user's control and that Pulsar can be managed independently of Streamvisor. The platform caters to both developers and platform engineers. Developers can accelerate product development by discovering and visualizing data flows, consuming and producing data, and managing subscriptions. Platform engineers can operate and scale infrastructure easily by accessing key metrics at a glance, administrating configurations and schemas, and securing applications with robust data governance features. In summary, Streamvisor provides a powerful and user-friendly interface for managing Apache Pulsar, offering features that enhance observability, streamline management, and bolster security. Its comprehensive toolset empowers organizations to efficiently operate their Pulsar environments, reduce operational disruptions, and ease Pulsar adoption across teams.
