Key-Value Store databaseTemporary: as memcached. The temporary key-value database stores the data in memory, which in two cases results in the loss of data, the first is the power outage, but the data content exceeds the memory size. The benefits of this treatment are very fast.Permanent type: such as Tokyo Tyrant, flare and RomaThe two are both types: Redis. Redis first data in memory, and then meet certain conditions (the default is 15 minutes more than 1 times,

benefits of temporary key-value storage and permanent key-value storage. Redis first saves the data to memory and writes the data to the hard disk when certain conditions are met (by default, more than 15 minutes, more than 10 in 5 minutes, and more than 10,000 key changes in 1 minutes). This ensures that the data in memory is processed, and that the data is persisted by writing to the hard disk. This type of database is particularly well suited for
