Optimize interface performance

  Eight key points of interface optimization

• Large amount of data , Batch operation data warehousing

• Consider asynchronous processing for time-consuming operations

• Use caching properly

• Optimize program logic 、 Code

• SQL Optimize

• Compress the transmission content

• Consider using files /MQ And so on , Asynchronous re landing DB

• It's most appropriate to discuss requirements with the product , The most comfortable way to achieve it

  One 、 Large amount of data , Batch operation data warehousing

Before optimization ：

//for Circular single entry 
for(TransDetail detail:list){  
    insert(detail);  
}

After optimization ：

//  Bulk warehousing ,mybatis demo Realization 
<insert id="insertBatch" parameterType="java.util.List">
insert into trans_detail( id,amount,payer,payee) values
 <foreach collection="list" item="item" index="index" separator=",">(
    #{item.id},	#{item.amount},
    #{item.payer},#{item.payee}
  )
</foreach>
</insert>

Two 、 Consider asynchronous processing for time-consuming operations </
