---------------------------------------------------------
However, it's still good to have a mechanism to filter out uncommitted log
files without reading the log blocks (e.g., add log instant time instead of
base instant time), to make such API and behavior easy to understand. Created

> HoodieMetadataTableValidator validation of the latest base files and file
> slices fails due to the following (from MT, log files are missing, compared
> to FS view). The validation failure may be due to the inflight compaction.
> Need to investigate whether this affects the file listing for write
> operations. The behavior is that after some instants, the validation can
> pass, so the MT correct is guaranteed, but the file listing view may have a
> bug.
