    11  ## Redis 优化方向
    12  
    13  ### 参数优化
    14  
    15  maxIdle设置高点，可以保证突发流量情况下，能够有足够的连接去获取redis，不用在高流量情况下建立连接
    16  
    17  **go-redis参数优化**
    18  
    19  ```yaml
    20    min_idle_conn: 30               
    21    dial_timeout: "1s"
    22    read_timeout: "500ms"
    23    write_timeout: "500ms"
    24    pool_size: 500
    25    pool_timeout: "60s"
    26  ```
    27  
    28  **redisgo参数优化**
    29  
    30  ```yaml
    31  maxIdle = 30
    32  maxActive = 500
    33  dialTimeout = "1s"
    34  readTimeout = "500ms"
    35  writeTimeout = "500ms"
    36  idleTimeout = "60s"
    37  ```
    38  
    39  ### 使用优化
    40  
    41  - 增加redis从库
    42  - 对批量数据，根据redis从库数量，并发goroutine拉取数据
    43  - 对批量数据大量使用pipeline指令
    44  - 精简key字段
    45  - redis的value存储编解码改为msgpack
    46
