IMPALA-13982: [WIP] Support views for Calcite planner in Impala
This patch adds the support for regular views to the Calcite planner
via adding a ViewTableMacro for each regular view in the given query
when populating the Calcite schema.
To be able to expand the view in ViewTableMacro, we need a newer
version of protobuf-java, e.g., 3.21.12. Currently 2.5.0 is
transitively pulled in by dependencies like
org.apache.hadoop:hadoop-hdfs. To address this issue, based on the
suggestion from Stamatis Zampetakis, we exclude avatica-core from the
artifacts that are pulled in by calcite-core, and explicitly add
avatica as a dependency, which already shades the protobuf-java it
requires to expand a view.
The patch supports the following cases, where functional.alltypes_view
is a regular view defined as "SELECT * FROM functional.alltypes".
1. select id from functional.alltypes_view
2. select alltypes_view.id from functional.alltypes_view;
3. select functional.alltypes_view.id from functional.alltypes_view;
Note that authorization for views is not yet supported.
