Redis vs Mongo – 简书

MongoDB vs. Redis Comparison

architecture – When to Redis? When to MongoDB? – Stack Overflow

caching – Is Redis just a cache? – Stack Overflow

Redis as the primary data store? WTF?!

• Redis is based on key-value pair

• save to：memory

• fast

• not reliable

• List, HashMap,List 构成的 distributed database

• 结构和关系：

• based on key-value pair

• database

• table

• tuple: tuple has strict schema limit

• Mongo is based on document

• save to：disk

• not so fast

• reliable

• 结构和关系：

• based on document

• database

• collection

• document: document is schemaless

结论：

• 如果优先考虑性能，且需要和有意愿花时间在性能优化上，那么用：Redis

• 如果是搭建原型且不需要太操心数据库的话，用：MongoDB
