Apache Pulsar

Apache Pulsar is an open-source, cloud-native distributed messaging and event-streaming platform developed by the Apache Software Foundation. It provides a scalable and reliable way to publish, store, and consume messages and real-time events across distributed applications. Apache Pulsar supports both traditional messaging and modern event-streaming use cases, making it suitable for microservices, real-time analytics, data pipelines, IoT applications, and other high-throughput systems.

Key Features of Apache Pulsar:

• Provides a distributed messaging and event-streaming platform for real-time applications.
• Supports both publish-subscribe messaging and queue-based messaging patterns.
• Provides persistent message storage for reliable data delivery.
• Supports high-throughput and low-latency messaging workloads.
• Provides multi-tenancy for securely managing multiple applications and teams.
• Supports topic partitioning for improved scalability and performance.
• Provides multiple subscription types, including Exclusive, Shared, Failover, and Key_Shared.
• Supports message acknowledgment and retention for reliable message processing.
• Provides geo-replication for distributing messaging workloads across multiple locations.
• Separates message serving from storage, allowing brokers and storage to scale independently.
• Supports authentication, authorization, and access control for secure deployments.
• Provides Pulsar Functions and connectors for integrating with external systems and applications.
• Includes command-line administration tools and REST APIs for managing Pulsar environments.
• Can be deployed in standalone mode for development and testing or as a distributed cluster for production workloads.
• Free and open-source with active community-driven development under the Apache Software Foundation.
