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.
