Dear administrator, I join in OSPP and am chosen by table-store project (https://summer-ospp.ac.cn/#/org/prodetail/225120149). Related Jira is https://issues.apache.org/jira/browse/FLINK-27626?jql=project%20%3D%20FLINK%20AND%20resolution%20%3D%20Unresolved%20AND%20text%20~%20%22pre-aggregation%22%20ORDER%20BY%20priority%20DESC%2C%20updated%20DESC .
Currently I am devoted to developping work. I have to create an FLIP to describe and discuss user interface. Therefore I am here to ask for permission to create a FLIP in Confluence(https://cwiki.apache.org/confluence/display/FLINK/Flink+Improvement+Proposals#FlinkImprovementProposals-Purpose). My account is hannankan and my email address is hannan...@foxmail.com. Best wishes!
