----------------------------------
Summary: Iceberg: Optimize show partitions through column
projection
Key: HIVE-28299
URL: https://issues.apache.org/jira/browse/HIVE-28299
Project: Hive
Issue Type: Improvement
Components: Iceberg integration
Reporter: Butao Zhang
In the current *show partitions* implementation, we need to fetch all columns
data, but in fact we only need two columns data, *partition* & {*}spec_id{*}.
We can only fetch the two columns through column project, and this can improve
the performance in case of big iceberg partition table.
