Ivan Daschinsky updated IGNITE-21100:
-------------------------------------
Component/s: python
> [Python Thin Client] Key class binary metadata registration is skipped
> ----------------------------------------------------------------------
>
> Key: IGNITE-21100
> URL: https://issues.apache.org/jira/browse/IGNITE-21100
> Project: Ignite
> Issue Type: Bug
> Components: python
> Affects Versions: python-0.6.1
> Reporter: Mikhail Petrov
> Priority: Major
>
> Python thin client does not register binary metadata for user classes that
> are used as a key for cache operations.
> It seems that it happens because
> 1. When we calculate hash code of a key object, we serialize it. The result
> is cached in `_buffer` attribute of the object. (see
> a) pyignite.datatypes.complex.BinaryObject.hashcode
> b) pyignite/binary.py#write_footer:203 ).
> The hash code of a key object is used to determine which node this key
> belongs to (PA).
> 2. But when we are about to send key object to the server side - we skip
> cache object serialization as the result is already saved in the buffer
> mentioned above AND skip its binary type registration.
> (see pyignite.datatypes.complex.BinaryObject.from_python_not_null)
