Connects via PostgreSQL wire protocol with a familiar SQL dialect, allowing seamless use of tools like psql and JDBC, and eliminates manual state tuning as highlighted in the README.

Uses S3 as primary storage for tables and processing state, enabling high performance, fast recovery, and dynamic scaling without expensive in-memory clusters, as described in the key design decisions.

Directly hosts and manages Apache Iceberg REST catalog, supporting continuous ingestion and built-in table maintenance like compaction, which promotes interoperability with open data lakehouses.

Performs incremental computations with end-to-end freshness under 100 ms and serves materialized views with 10–20 ms p99 latency, ideal for real-time dashboards and monitoring.

Integrates real-time ingestion, stream processing, and low-latency serving in a single system, simplifying architecture and reducing operational overhead for unified analytics.
