For the string performance optimization scheme, I organized all Java frameworks into PDF

The framework of this paper is as follows

The first part , Mainly in the process of reading the code log and notes ;

The second part , It mainly introduces Redis The main framework of , as well as Redis How services are provided , Start with the simplest command ;

The third part , This paper mainly introduces Redis The underlying data structure used for storage , This part is very interesting ;

The fourth part , Mainly explained Redis Core functions , Including persistence , subscribe / Release pattern , Master slave copy , Transaction mechanism , Clusters, etc. ;

The fifth part , It shows Redis A few simple applications ;

The sixth part , It introduces Redis and Memcached The difference between , And a little bit about Memcached.
