Can you share some code and the actual errors you’re getting? It’s not entirely 
clear to me what you’re trying to do? Are you using the new Python thin-client? 
Or are you using Spark's Python support along with Ignite’s support for 
DataFrames? And what do you mean by “complex object type”?

Regards,
Stephen
