redis--事务--底层实现

一、redis的事务结构

typedef struct multiState {
multiCmd *commands;     /* 命令的数组 */
int count;              /* 事务的命令 */
int minreplicas;        /* MINREPLICAS for synchronous replication */
time_t minreplicas_timeout; /* MINREPLICAS timeout as unixtime. */
} multiState;

typedef struct multiCmd {
robj **argv;   /*参数*/
int argc;      /*参数的个数*/
struct redisCommand *cmd;  /*命令*/
} multiCmd;
