[GitHub] [hudi] bithw1 opened a new issue, #8359: [SUPPORT]What's the behavior when doing flink query hudi table with read.end-commit set and read.start-commit not set

   Hi,
   
   I have a hudi table of COW type.
   
   The table has 5 commits, and one letter is inserted in each commit
   
   
   ```
         20230402180146498 A
         20230402180157572 B
         20230402180209196 C
         20230402180218522 D
         20230402180228801 E
   ```
   
   Then, I execute a flink query against this table with the reading option, `'read.end-commit'='20230402180209196'`(the third commit)
   
   From the result, only C are queried out, A and B are not queried out.
   
   I have thought it is a snapshot query until time `20230402180209196`, that is, A,B,C should be queried out.
   
   
   I would ask what's the behavior  with `read.end-commit set and read.start-commit not set`, how to unserstand the query result,
   
   Thanks.

   By default, the `read.start-commit` is the latest commit on the Hudi table, since you also declare the `read.end-commit`, then `read.start-commit` should equal to `read.end-commit`, finally, only the `read.end-commit` is queried and output.
