When Redis is not a good fit
Redis is an in-memory data structure store commonly used as a cache, database and message broker, known for very low-latency reads and writes. Its licensing has changed several times: from the original 3-clause BSD license, through Commons Clause and Redis Source Available License phases, to a dual source-available licensing model adopted in March 2024, meaning current versions of Redis itself are not fully open source. Redis Cloud, the managed service, has a free plan and usage-based paid plans starting around $5 a month.
It is a weaker choice for:
- Teams that specifically need a permissively licensed, traditionally open source in-memory store, given Redis's move to a source-available license in 2024, where a fork like Valkey may fit better
- Very large primary datasets that don't fit comfortably in memory, without using auto-tiering features
- Applications that need complex relational queries, joins or strong ACID guarantees across many tables
