NOTE: official binary wheels are linked against openssl statically for remote objection store communication. Please file Github issue to request for critical openssl upgrade.
Usage
Resolve partitions for current version of the DeltaTable:
>>> from deltalake import DeltaTable
>>> dt = DeltaTable("../rust/tests/data/delta-0.2.0")
>>> dt.version()
3
>>> dt.files()
['part-00000-cb6b150b-30b8-4662-ad28-ff32ddab96d2-c000.snappy.parquet', 'part-00000-7c2deba3-1994-4fb8-bc07-d46c948aa415-c000.snappy.parquet', 'part-00001-c373a5bd-85f0-4758-815e-7eb62007a15c-c000.snappy.parquet']
Convert DeltaTable into PyArrow Table and Pandas Dataframe:
>>> from deltalake import DeltaTable
>>> dt = DeltaTable("../rust/tests/data/simple_table")
>>> df = dt.to_pyarrow_table().to_pandas()
>>> df
id
0 5
1 7
2 9
>>> df[df['id'] > 5]
id
1 7
2 9
Time travel:
>>> from deltalake import DeltaTable
>>> dt = DeltaTable("../rust/tests/data/simple_table")
>>> dt.load_version(2)
>>> dt.to_pyarrow_table().to_pandas()
id
0 5
1 7
