Internal Tables (Coming Soon) Internal Tables are topics inside StreamNative Cloud that store data in Ursa Format, the native, high-performance storage layer used by StreamNative’s Ursa engine. This capability is currently not available and will be released in an upcoming version of StreamNative Cloud. Key Characteristics
  • Stored in Ursa Format - Data is written using a compact, high-throughput format optimized for streaming and low-latency access.
  • Fully Managed by StreamNative - StreamNative will handle all storage lifecycle operations — retention, compaction, indexing, and metadata.
  • StreamNative-Native Performance - Designed for fast ingestion, low latency, and operational efficiency within the StreamNative cloud environment.
  • Not Externally Queryable via Open Table Formats - Internal Tables are optimized for streaming workloads, not external analytics engines.
When to Use Internal Tables
  • You need low-latency ingestion and high-throughput streaming.
  • You prefer StreamNative to manage all storage operations end-to-end.
  • You don’t require external interoperability with Iceberg/Delta or an external Lakehouse system.
Note: Internal Tables are under development and will be introduced soon. The feature description above outlines planned capabilities.
