Hello,
Firstly I describe what I learn about the process of a query as follow: When there comes a sql with filter like “select * from A where A.a in (“a”,”b”,”c)” , there exists three steps to do, Step1, Carbon index file could locate the corresponding Carbon data file that satisfy our query, and I believe that Carbon index could quickly locate the data by using startkey and endky. Step2, footer of those Carbon data files could locate the corresponding Blocket that satisfy our query Step3, Blocket could locate the corresponding row in it that satisfy our query as this column is sorted. So now I have a question for step1, how could carbon create the startkey and endkey just using the provided filter condition like A.a in (“a“，”b”, “c”)? Great thanks, Chao
