          return MutationsBatcher(self, flush_count, max_row_bytes)
docs: Factory to create a mutation batcher associated with this instance.
  
          For example:
  
          .. literalinclude:: snippets_table.py
              :start-after: [START bigtable_mutations_batcher]
              :end-before: [END bigtable_mutations_batcher]
  
          :type table: class
          :param table: class:`~google.cloud.bigtable.table.Table`.
  
          :type flush_count: int
          :param flush_count: (Optional) Maximum number of rows per batch. If it
                  reaches the max number of rows it calls finish_batch() to
                  mutate the current row batch. Default is FLUSH_COUNT (1000
                  rows).
  
          :type max_row_bytes: int
          :param max_row_bytes: (Optional) Max number of row mutations size to
                  flush. If it reaches the max number of row mutations size it
                  calls finish_batch() to mutate the current row batch.
                  Default is MAX_ROW_BYTES (5 MB).
