        Creates a new RedisSinkFunction that connects to the Redis server.
        参数:
        flinkConfigBase - The configuration of FlinkConfigBase
        redisSinkMapper - This is used to generate Redis command and key value from incoming elements.

            throws Exception
        Called when new data arrives to the sink, and forwards it to Redis channel. Depending on the specified Redis data type (see RedisDataType), a different Redis command will be applied. Available commands are RPUSH, LPUSH, SADD, PUBLISH, SET, SETEX, PFADD, HSET, ZADD.
        参数:
        input - The incoming data
        抛出:
