场景情况:
统计一些数据,分别放入200+个库中
当每个库中的数据量10W以上的时候,有的数据库插入就会变慢
加了慢日志,了解了各个字段的说明,但是没有分析出慢的原因,哪位大佬帮看看
谢谢

代码:
for db_key, insert_data_content := range db_name_to_insert_data{
each_start := time.Now().UnixNano()
err := dbvisit.InsertDataList(map[string]interface{}{“content”: insert_data_content, “dbname”: db_key, “tablename”: SERVER_TRAFFIC_FLOW_LOG_TB})
each_use := (time.Now().UnixNano()-each_start)/1e6
if each_use > 50{
slow_count += 1
adframe.AddMustLog(“—-Insert Server Ip DataList:”, err, db_key, len(insert_data_content), “use time:”,each_use, “(ms)”)
}

插入数据用的自己的框架
mongo慢日志如下:
