What Is KWDB

KWDB is an open source distributed multi-model database project incubated by OpenAtom Foundation for AIoT, industrial IoT, energy, connected vehicles, and operations monitoring scenarios. KWDB focuses on managing time-series data and relational data in one database instance.

If you are searching for “what is KWDB”, think of it as a data foundation for analyzing device metrics, tags, and business dimension tables together.

What Problems Does KWDB Solve​

IoT systems often store time-series readings in one database and device metadata, sites, users, and business rules in another relational database. That split creates data synchronization work, cross-system joins, permission complexity, and higher operational cost.

KWDB focuses on:

  • Creating time-series and relational databases in the same instance.
  • Querying metrics, tags, and business dimensions with SQL.
  • Supporting high-concurrency writes and large-scale time-series queries.
  • Providing a unified entry point for deployment, inspection, AI Agent workflows, and developer tools.

Common Use Cases​

KWDB fits scenarios that need to process device metrics and business relational data together:

  • Smart meters, sensors, production equipment, and telemetry.
  • Correlating device readings with device profiles, regions, and alert rules.
  • Real-time query and historical analysis for industrial IoT platforms.
  • Developer workflows that combine SQL examples, sample data, and Agent Skills.
