[jira] [Created] (IMPALA-11692) Struct slot memory sharing involving select * not working properly
Daniel Becker created IMPALA-11692:
--------------------------------------
Summary: Struct slot memory sharing involving select * not working properly
Key: IMPALA-11692
URL: https://issues.apache.org/jira/browse/IMPALA-11692
Project: IMPALA
Issue Type: Bug
Reporter: Daniel Becker
Assignee: Daniel Becker
With EXPAND_COMPLEX_TYPES=1, if there are structs coming from the star expansion and members of the structs are also given explicitly, slot memory sharing does not work in some cases:
{code:java}
explain select * from functional_orc_def.complextypes_nested_structs;
row-size=64B{code}
{code:java}
explain select *, outer_struct.inner_struct1 from functional_orc_def.complextypes_nested_structs;
row-size=80B{code}
The row size should be the same in both cases as outer_struct.inner_struct1 is part of outer_struct which is included in the star.
