Compare Apache Pulsar vs. HiveMQ

Apache Pulsar is a cutting-edge, distributed platform for messaging and streaming that was initially developed at Yahoo! and has since become a prominent project under the Apache Software Foundation. It boasts straightforward deployment, a lightweight computing process, and APIs that are user-friendly, eliminating the necessity of managing your own stream processing engine. For over five years, it has been utilized in Yahoo!'s production environment, handling millions of messages each second across a vast array of topics. Designed from the outset to function as a multi-tenant system, it offers features like isolation, authentication, authorization, and quotas to ensure secure operations. Additionally, Pulsar provides configurable data replication across various geographic regions, ensuring data resilience. Its message storage relies on Apache BookKeeper, facilitating robust performance, while maintaining IO-level separation between read and write operations. Furthermore, a RESTful admin API is available for effective provisioning, administration, and monitoring tasks, enhancing operational efficiency. This combination of features makes Apache Pulsar an invaluable tool for organizations seeking scalable and reliable messaging solutions.

The HiveMQ Platform provides a scalable, reliable data backbone with an event-driven MQTT architecture. Here are a few highlights: 1. MQTT Broker: At the heart of the HiveMQ platform is a fully MQTT-compliant broker purpose-built for fast, reliable, bi-directional data movement between IoT devices and enterprise systems. 2. Edge Data Integration: HiveMQ Edge seamlessly integrates edge data by converting industrial protocols into standardized MQTT, enabling an interoperable IIoT infrastructure. 3. IoT Streaming Governance: Data Hub transforms data in flight, passing only the most relevant, contextualized data to cloud and enterprise systems. 4. UNS & IT/OT convergence Enabler: Commonly used as the backbone for Unified Namespace architectures and seamlessly connects OT devices with IT systems for full visibility and interoperability. 5. Distributed Data Intelligence: HiveMQ Pulse unifies and contextualizes data across the enterprise for smarter decisions exactly where they matter most. 6. Maximum Interoperability: Runs anywhere on-premises or in public or private clouds. Efficiently connects to streaming applications, databases and data lakes with a Java SDK to build your own 7. Scalability to Support Growth: Elastic scaling with automatic data balancing and smart message distribution. Proven benchmark of up to 200M active clients with 1.8B messages/hour 8. Business Critical Reliability: Zero message loss with persistence to disk and offline queuing. No single point of failure due to masterless cluster architecture and zero downtime upgrades
