> Currently,  we table store has introduced a `RollingFile` to write an iterator of rows into the underlying files.  That's suitable for the memory store flush processing, but for append-only table, it usually don't have any memory store to cache those branch of rows temporarily, the idea approach is writing one record into the columnar writer each time, and the columnar writer will cache them  and write into the underlying file in one batch.
