#Accessing redis or  redis Cluster using the xRedisClusterClient class

#include "xRedisClusterClient.h"
int main(int argc, char **argv) {
    xRedisClusterClient redisclient;
    # Connect to REDIS and establish a connection pool 
    # If this node is a member of the REDIS cluster, 
    # a connection pool is automatically established for each primary node in the cluster.
    std::string passwd = "passwd123";
    bool bRet = redisclient.connect("127.0.0.1", 6379, passwd, 4);

    RedisResult result;
    redisclient.command(result, "set %s %s", "key", "hello");
    
    printf("type:%d integer:%lld str:%s \r\n",
        result.type(), result.integer(), result.str());

   while (true) {
        usleep(1000*1000*6);
        redisclient.keepalive();
    }

    return 0;
