# Cons of Redis

**Dependency on the application memory.** Total reliance and dependency on the application memory is a real drawback. That is to say, your database will crash if its size exceeds the size of available memory.

**No support for query language or joins.** Regarding compatibility with other dataset types, Redis lags behind. Given that at some time your business may need scaling and using other data formats, having rapid entries as a single option leaves this issue open.
