In their own words
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.
