Load a Deltalake table data from an S3 path.

This function requires the deltalake package. See the How to load a Delta table guide for loading instructions.

Parameters:

path (Optional[str]) – The path of the DeltaTable.
version (Optional[int]) – The version of the DeltaTable.
partitions (Optional[List[Tuple[str, str, Any]]) – A list of partition filters, see help(DeltaTable.files_by_partitions) for filter syntax.
columns (Optional[List[str]]) – The columns to project. This can be a list of column names to include (order and duplicates are preserved).
without_files (bool) – If True, load the table without tracking files (memory-friendly). Some append-only applications might not need to track files.
boto3_session (Optional[boto3.Session()]) – Boto3 Session. If None, the default boto3 session is used.
s3_additional_kwargs (Optional[Dict[str, str]]) – Forwarded to the Delta Table class for the storage options of the S3 backend.
pyarrow_additional_kwargs (Optional[Dict[str, str]]) – Forwarded to the PyArrow to_pandas method.

Returns:

df – DataFrame with the results.

Return type:

pd.DataFrame
