[SUPPORT]What's the behavior when doing flink query hudi table with read.end-commit set and read.start-commit not set

[bithw1]

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), I didn't set the option 'read.start-commit

I have thought it is a snapshot query until time 20230402180209196, that is, A,B,C should be queried out, but from the result, only C is queried out, A and B are not 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.
