Araika Singh updated HIVE-28601:
--------------------------------
Description:
Currently, the Hive Metastore (HMS) provides the {{getPartitionsWithSpecs}}
API, which allows fetching a list of partitions with selective sub-objects as
needed.
However, certain API calls within HiveServer2 (HS2) only require specific
elements, such as the location, without needing the complete storage
descriptor. Transmitting the full object in these cases results in unnecessary
overhead and resource consumption.
The doc along with Jira is added for detailed information on the motivation
behind it, along with the performance impact on a smaller level.
