Evgenii Zhuravlev updated IGNITE-12809:
---------------------------------------
Description:
Reproducer attached.
If result set is bigger than a page size(1 by default) and there are more than
10 fields in an object, then, for all rows after the first query column order
will be wrong. Looks like column order is being sorted as a string instead of
number.
The reason for that is a sorting in api/sql.py:
https://github.com/apache/ignite/blob/master/modules/platforms/python/pyignite/api/sql.py#L445
If you remove it, everything will work fine. We need to make sure that this is
the right solution for this issue.
