When NOT to use tidb

  • If your primary focus is on a traditional relational database with limited transactional and minimal analytics needs, TiDB's complexity and overhead may not be justified.
  • 如果你的主要重点是传统的具有有限事务处理和少量分析需求的关系型数据库，TiDB的复杂性和开销可能是不必要的。

Choose redis if…

  • redis is primarily C; tidb is Go.
  • License: redis is Other, tidb is Apache-2.0.
  • Tags unique to redis: cache, json, nosql, in-memory.
  • You need high-speed access to frequently used data due to Redis's in-memory nature.

When NOT to use 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.
