When should I avoid redis?

Your project has limited memory resources since Redis relies on in-memory storage, which could lead to high costs or operational challenges with large datasets. You prioritize persistence over speed; while Redis offers persistence options, its primary design is for real-time access and not robust disk-based backup solutions like traditional SQL databases. Your application workload does not benefit from the fast read/write capabilities and rich data structure support offered by Redis, possibly implying that a less specialized database would suffice.

When should I avoid RediSearch?

With an application that exclusively needs basic caching features without advanced querying, as RediSearch adds overhead not justified in such cases. In environments where the storage and querying of unstructured data is minimal to non-existent, making full-text search capabilities redundant. For teams or applications that prefer or require a cloud-managed solution for vector similarity searches without wanting to manage Redis. If your project uses another database system not based on Redis and you're looking for a tightly integrated query engine.
