+        Iterates through the symbol in row chunks. When run in a loop, each chunk is returned as a separate dataframe.

+        If `num_chunks` or `rows_per_chunk` are specified, they will be used to set the chunk size. If neither are

+
+        Reading in chunks can be used to control memory usage for large data sets or to process chunks using a compute

+
+        Parameters
+        ----------
+        symbol : str
+            Symbol name.
+
+        as_of : AsOf, default=None
+            Return the data as it was as of the point in time. ``None`` means that the latest version should be read.
+            See `read()` for more detail.
+
+        date_range: Tuple[Optional[Timestamp], Optional[Timestamp]], default=None
+            Not yet implemented for chunks.
+            DateRange to restrict chunks to. See `read()` for more detail.
+
+        row_range: `Optional[Tuple[int, int]]`, default=None
+            Row range to restrict chunks to. See `read()` for more detail.
+
+        columns: List[str], default=None
+            Determines which columns to return data for. See `read()` for more detail.
+
+        query_builder: Optional[QueryBuilder], default=None
+            A QueryBuilder object to apply to each chunk read. See `read()` for more detail on QueryBuilder.
+            Note that in some cases this will lead to different results from applying the same query_builder to
+            the whole data set for the symbol.
+
+        lazy: bool, default=False
+            If True, return lazy dataframes rather than data. See `read()` for more detail.
+
+        num_chunks: int
+            The number of chunks to divide the data into. Do not use with `rows_per_chunk`.
+
+        rows_per_chunk: int
+            The number of rows in each chunk. Do not use with `num_chunks`.
+
+        Returns
+        -------
+        An iterator for which each iteration will yield the dataframe from a chunk.
+
+        Examples
+        --------
