Main Features

• Push real-time data to your apps

  By subscribing to streams in HStreamDB, any update of the data stream will be pushed to your apps in real time, and this promotes your apps to be more responsive.

  You can also replace message brokers with HStreamDB and everything you do with message brokers can be done better with HStreamDB.

• Stream processing with familiar SQL

  HStreamDB provides built-in support for event-time based stream processing. You can use your familiar SQL to perform basic filtering and transformation operations, statistics and aggregation based on multiple kinds of time windows and even joining between multiple streams.

• Easy integration with a variety of external systems

  With connectors provided, you can easily integrate HStreamDB with other external systems, such as MQTT Broker, MySQL, Redis and ElasticSearch. More connectors will be added.

• Real-time query based on live materailze views

  With maintaining materialized views incrementally, HStreamDB enables you to gain ahead-of-the-curve data insights that response to your business quickly.

• Reliable persistent storage with low latency

  With an optimized storage design based on LogDevide, not only can HStreamDB provide reliable and persistent storage but also guarantee excellent performance despite large amounts of data written to it.

• Seamless scaling and high availability

  With the architecture that separates compute from storage, both compute and storage layers of HStreamDB can be independently scaled seamlessly. And with the consensus algorithm based on the optimized Paxos, data is securely replicated to multiple nodes which ensures high availability of our system.
