🧊 A curated list of OLAP databases, data lake tools, columnar engines, and analytics frameworks for data engineers.
Graph database native to the cloud. Embedded, multi-tenant, built on object storage.
Fast, minimal, and ergonomic zero-copy Apache Arrow tabular data implementation in Rust, with PyO3, Python bindings, NdArray, XArray, shared-memory and low-latency SIMD for data-engineering and columnar workloads. Bridge to Polars and Arrow-rs over FFI effortlessly.
C-Store : A column-oriented DBMS prototype (frozen)
In-memory, columnar, arrow-based database.
Uni is a modern, embedded database that combines property graph (OpenCypher), vector search, and columnar storage (Lance) into a single, cohesive engine. It is designed for applications requiring local, fast, and multimodal data access, backed by object storage (S3/GCS) durability.
