In their own words
Lightstreamer
Lightstreamer is an event broker for delivering real-time data to web and mobile applications, including across proxies, firewalls, disconnections, and network congestion. Intelligent Streaming adjusts data flow to network conditions and can resample or combine updates to keep users synchronized. Messaging options include publish/subscribe, request/response, client-to-server messaging, and fine-grained item and field subscriptions. StreamSense chooses WebSockets or HTTP connections for each client, including through restrictive firewalls and legacy proxies.
Ready-made connectors cover Kafka, MQTT, and JMS, with named examples including Confluent Cloud, Amazon MSK, Redpanda, AWS IoT Core, IBM MQ, and ActiveMQ. Custom adapters can be built with Java, Python, Node.js, .NET, and TCP sockets. Lightstreamer supports TLS, certificates, mutual authentication, and custom authentication and authorization. It can be deployed on-premises or in the cloud, with Helm, Docker, and Kubernetes support. Monitoring options include a web dashboard, configurable logs, JMX, Prometheus, and Grafana integrations. The free Non-Production Limited License requires a Production License and a server restart after at most 210 minutes of uptime.
Pravega
Pravega is an open-source, self-hosted storage system built around durable append-only streams for continuous, unbounded data. Streams hold parallel byte sequences, can scale as ingestion changes, and use automatic tiering to scale-out storage. Data may be retained indefinitely, allowing applications to read current and historical events. Pravega describes exactly-once delivery and processing with ordering guarantees despite client, server, or network failures, and transactions can write event sets atomically. It targets streaming applications, IoT data, and batch or interactive analytics. Connectors are listed for Apache Flink, Spark, Hadoop, Presto, Boomi, and Apache NiFi; client languages include Java, Rust, and Python. Deployment options include a single-process standalone server or distributed mode with Docker Compose. Distributed production deployments list Java 11, supported long-term storage, ZooKeeper 3.6.3, and BookKeeper 4.14.1. TLS and role-based access control are configurable.
