Project Roadmap

For the latest status on implementation and planned features, please refer to the ROADMAP.md in the GitHub repository.

Future Phases

Multi-Column Indexes

We are currently researching the implementation of Composite Scalar Indexes (pre-computed roaring bitmaps for common multi-column filters) and Multi-Vector Search (simultaneous ranking across multiple embedding columns).

Distributed Query Engine

Future versions of HyperStreamDB will include a distributed query planner capable of coordinating multiple serverless execution nodes for ultra-large datasets.

Native Spark and Trino Connectors

Native integration for distributed SQL engines to leverage HyperStreamDB sidecar indexing.
