Vector search · full-text ranking · graph traversal · sandboxed Python — one SQL engine, one query. Paro is a multi-model database written in Rust. It unifies relational, vector, full-text, and graph workloads — no sidecar services, no cross-system glue code. A single SQL statement can walk a social graph, rank documents by keyword relevance, re-rank by embedding similarity, and invoke a sandboxed Python UDF — served from a consistent snapshot while concurrent writers commit under serializable isolation. [!WARNING] Paro is currently in beta. Expect rough edges in driver/ORM compatibility, steady-state performance, and on-disk format stability. Best used for evaluation and prototyping today — not production-critical workloads yet. Features - Multi-model — structured and semi-structured data as first-class citizens in one engine. - Columnar storage — column-oriented layout optimized for scan-heavy analytical workloads. - SIMD execution — vectorized compute kernels exploiting hardware-level parallelism for distance functions, expression evaluation, and more. - SQL-first — PostgreSQL wire protocol and a familiar SQL dialect; psql works well today, while broader driver and ORM compatibility is still being validated. - Vector search — pgvector-compatible operators ( , , , ) with HNSW indexing. - Full-text search — GIN indexes, to tsvector , plainto tsquery , ts rank , and BM25 ranking. - Graph queries — SQL/","default_branch":null,"files":null,"tree":[],"storefront":"/r/zunor","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/zunor/paro/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
