IMPALA-9499: Display support for all complex types in a SELECT * query
This change adds EXPAND_COMPLEX_TYPES query option to support the
display of complex types in SELECT statements where star (*) expression
is in the select list. The query option changes the behaviour of star
expansion to list all top-level complex column fields, instead of
listing the scalar column fields only. Nested complex type expansion is
also supported, eg.: struct.* will enumerate the nested collections
inside struct. Array and struct collection types are supported.
Testing:
- Analyzer tests check the proper expansion of complex types when the
query option is enabled.
- EE tests check the proper complex type deserialization when the query
option is enabled, and the original behaviour when the option is
disabled.
