Redis design and implementation reading notes a Redis string

1 Redis is implemented in C language

2 C string is the/0 end of the character array

3 Redis-specific dynamic string implementations

/*/struct  sdshdr         Space-occupied length int in {// buf      len;     // Length of remaining free space in buf    int  Free ;     // Data Space    Char buf[];};

Sdshdr

Free 0

Len 5

Buf

--->

R

E

' d '

I

' s '

'/0 '

4 feel more like the design of StringBuffer in Java
