ParadeDB Enterprise offers commercial licensing for additional features and support.. - Requirements: Min 2 GB RAM; Requires Docker; Installation can be done locally in a fresh Docker container.; For deployment, check out the hosting options provided by ParadeDB.. - Tags unique to paradedb: aggregations, analytics, bm25, columnar-storage. - Also covers Data & Retrieval. - When you need a PostgreSQL extension that supports full-text search, vector retrieval, and aggregations in a single database. ### Choose pgvecto.rs if… - License: pgvecto.rs is Apache-2.0, paradedb is AGPL-3.0. - Tags unique to pgvecto.rs: chatgpt, faiss, gpt, hacktoberfest. - When you need to integrate vector search capabilities directly into an existing PostgreSQL database, as pgvecto.rs extends PostgreSQL with vector data types and distance calculations. ## When NOT to use paradedb - If your project strictly requires a standalone vector database without the need for full-text search or aggregations. - When you prefer a solution that does not come with the GNU Affero General Public License v3.0, as this might not align with your licensing requirements. - If your application does not require real-time analytics or hybrid search capabilities, and you are looking for a simpler solution. - For scenarios where you need a distributed search solution that operates independently of PostgreSQL. ## When NOT to use pgvecto.rs - If your application does not require integration with PostgreSQL, as pgvecto.rs is specifically designed as an extension for PostgreSQL and does not offer standalone vector search capabilities. - When you need a solution that supports vector dimensions beyond 65535, as pgvecto.rs is limited to this maximum dimension size. - If you are looking for a solution that does not require the overhead of setting up and maintaining a PostgreSQL database, as pgvecto.rs is tightly coupled with PostgreSQL. - When you need a vector database that supports more complex vector operations beyond the three distance calculations provided by pgvecto.rs. ## Common questions ### What is the difference between paradedb and pgvecto.rs? paradedb: One Postgres for application data, full-text search, vector retrieval, and aggregations. pgvecto.rs: Scalable, Low-latency and Hybrid-enabled Vector Search in Postgres.
