>  When data batch comes to carbon, carbon will check
> whether the batch id of the data is already committed. If yes, skip this batch,
> otherwise convert data fields and append to row format file directly. So, the
> records are either flushed or not flushed, data consistency is ensured.
> When writing to the row format file, carbon will convert the data fields the same way
as for
> columnar format, like global dictionary conversion, timestamp conversion, complex type
> conversion, etc.
