redis source code analysis

Recently, there is no substantive work, just a little time, want to learn other people's code. Also saw a bit of source code, is a bit of reading experience, so determined to see the spring of this large-scale project source code, learn its design ideas. Hand

In the previous article, detailed description of the source code of HashMap and HashSet, from the point of view of the source can be seen in the depth of the relationship between the two, speculation, Linkedhashmap and Linkedhashset must also have in-depth contact. After analysis you will find that the relationship bet
