Which one has faster reading speed, mongodb or redis?

Collection Like

The read speed of redis is faster than mongodb. Reasons include: 1. redis uses simple key-value storage, while mongodb stores data in json format, which requires parsing and deserialization. 2. Redis uses hash tables to quickly find data, while mongodb uses b-tree indexes. Therefore, redis is a better choice in applications that require high-performance read operations.
