Summary: When making changes in stats collection path and now cross validating raw/logical size calculation from vector and field writer collection, we found some test failures in feature reaper tests due to test data specifying inconsistent input vector type and schema type. The writer supports this upcast implicitly otherwise, so the right thing to do is to support it in a lightweight fashion. We do still have to fix the test case where it tried to pass integer to a float column. Differential Revision: D91559828
Summary: As we went through the current validations, we can start to deprecate the current top level raw size accounting from the input vector and use the logical size from root column stats instead. We do so via a flag in writer options, which can then be wired up in the different downstream call sites. Still leaves the flag on for continuous e2e validation (vader). Differential Revision: D91559827
Summary: Fix passthrough flatmap raw size accounting in mainly two issues: * string flatmap keys * constant encoding Now raw size accounting is fully consistent with field writer stats collection. Differential Revision: D92242565
