hstream

Hstream is an open-source stream processing platform designed for real-time data analysis and processing. It provides a robust and scalable solution for handling high-volume, high-velocity data streams from various sources. The platform is built on a distributed architecture, allowing it to process data across multiple nodes for increased performance and fault tolerance.

At its core, Hstream uses a declarative approach to define stream processing logic. Users can write processing pipelines using a SQL-like query language, which simplifies the development of complex data transformations, aggregations, and filtering operations. This declarative nature also aids in optimizing query execution and resource utilization.

Key features of Hstream include its ability to ingest data from diverse sources such as Kafka, Pulsar, and cloud storage services. It supports various output sinks for processed data, enabling integration with downstream systems like databases and data warehouses. Hstream also offers features for state management, allowing applications to maintain and access state across processing steps, which is crucial for sophisticated analytics like windowing and pattern detection.

The platform is designed with extensibility in mind, allowing developers to integrate custom functions and connectors. Its commitment to open-source principles fosters community collaboration and continuous improvement. Hstream aims to provide a flexible and efficient environment for building real-time data applications that can scale to meet demanding production requirements.
