IMPALA-12612: SELECT * queries expand complex type columns from Iceberg metadata tables Similarly to how regular tables behave, the nested columns are omitted when we do a SELECT * on Iceberg metadata tables and the user needs to turn EXPAND_COMPLEX_TYPES on to include the nested columns into the result. This patch changes this behaviour to unconditionally include the nested columns from Iceberg metadata tables. Note, the behavior of handling nested columns from regular tables doesn't change with this patch. Testing: - Adjusted the SELECT * metadata table queries to add the nested columns into the results. - Added some new tests where both metadata tables and regular tables were queried in the same query.

Lightning-fast, distributed SQL queries for petabytes of data stored in open data and table formats.
Impala is a modern, massively-distributed, massively-parallel, C++ query engine that lets you analyze, transform and combine data from a variety of data sources:
The fastest way to try out Impala is a quickstart Docker container. You can try out running queries and processing data sets in Impala on a single machine without installing dependencies. It can automatically load test data sets into Apache Kudu and Apache Parquet formats and you can start playing around with Apache Impala SQL within minutes.
To learn more about Impala as a user or administrator, or to try Impala, please visit the Impala homepage. Detailed documentation for administrators and users is available at Apache Impala documentation.

Impala only supports Linux at the moment. Impala supports x86_64 and has experimental support for arm64 (as of Impala 4.0). Impala Requirements contains more detailed information on the minimum CPU requirements.
Impala runs on Linux systems only. The supported distros are
Other systems, e.g. SLES12, may also be supported but are not tested by the community.
This distribution uses cryptographic software and may be subject to export controls. Please refer to EXPORT_CONTROL.md for more information.
