Wes McKinney closed ARROW-9039.
-------------------------------
Resolution: Won't Fix
> py_bytes created by pyarrow 0.11.1 cannot be deserialized by more recent
> versions
> ---------------------------------------------------------------------------------
>
> Key: ARROW-9039
> URL: https://issues.apache.org/jira/browse/ARROW-9039
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.11.1, 0.15.1
> Environment: python, windows
> Reporter: Yoav Git
> Priority: Minor
>
> I have been saving dataframes into mongodb using:
> {{import pandas as pd; import pyarrow as pa}}
> {{df = pd.DataFrame([[1,2,3],[2,3,4]], columns = ['x','y','z'])}}
> {{byte = pa.serialize(df).to_buffer().to_pybytes()}}
> and then reading back using:
> {{df = pa.deserialize(pa.py_buffer(memoryview(byte)))}}
> However, pyarrow is not back-compatible. i.e. both versions 0.11.1 and 0.15.1
> can read their own pybytes created by it. Alas, they cannot read each other.
