Redis vs ClickHouse: Choosing the Right Vector Database for Your Needs

Redis and ClickHouse are two popular vector databases that offer efficient similarity searches, making them crucial in AI applications. While both have vector search capabilities, they differ in their core technologies, features, and use cases. Redis is an in-memory database with hybrid search capabilities, combining vector similarity search with traditional filtering on other attributes. It's great for real-time applications that need low latency and can handle datasets that fit in memory. ClickHouse, on the other hand, is an open-source column-oriented database designed for real-time analytics with full SQL support. It can handle large-scale vector datasets and combines vector search with metadata filtering or aggregation. The choice between Redis and ClickHouse depends on specific use cases, considering data volume, query complexity, response time, and integration requirements.
