What is fixed_string mean in vid_type?

[aminmaghsodi]

Hi, In documentation of CRUD section, there is a notation that we should define vid_type, which could be FIXED_STRING(N). My question is about N parameter. What happens, when we define for example N = 10 then we put a key with length N = 2? Are those extra 8 bytes allocated and we have waste of disk usage or they will be ignored and just (2 * size of string) is allocated?

Define N=10, if the length is less than 10, it will automatically fill in'\0'. Allocate space for '\0', but do not count the length of the string. Same as char(N) in SQL
