Review Comment:
If the connector option is not specified, Flink will creates a Managed table.
Managed table relies on checkpoint to commit and the data is visible only
after commit.
Managed table requires two layers of log storage and file storage and
depends on the flink table store, CTAS will support Managed Table in the future.
