For your information, While drafting the upcoming quarterly report, I found there are three talks that are directly related to Hadoop in this year's ApacheCon Asia. https://apachecon.com/acasia2021/tracks/bigdata.html
Bigtop 3.0: Rerising community driven Hadoop distribution <https://apachecon.com/acasia2021/sessions/1152.html> Technical tips for secure Apache Hadoop cluster <https://apachecon.com/acasia2021/sessions/1116.html> Data Lake accelerator on Hadoop-COS in Tencent Cloud <https://apachecon.com/acasia2021/sessions/1124.html> There are other relevant talks in the Big Data track, including Ozone, Impala, Parquet and so on. I am sure you'll find the talks useful. The ApacheCon will take place online virtually between Aug 6-8. Thanks, Wei-Chiu
