"Application of Apache Doris in JD.COM"_Apache Doris Summit 2022

JD.COM's Search & Push Project started in 2019. Its goal is to bring better exposure and clicks to the high-quality goods resources of merchants on the platform through traffic control. Since joining the project, Apache Doris has been responsible for the traffic in JD.COM's Double 11 and 6.18 promotions during the past three years, with the traffic peaks reaching 450 million per minute.
