-------------------------------------
Summary: Support server-side scan planning of Iceberg
Key: HIVE-29599
URL: https://issues.apache.org/jira/browse/HIVE-29599
Project: Hive
Issue Type: Improvement
Components: Iceberg integration, Standalone Metastore
Reporter: Shohei Okumiya
Assignee: Shohei Okumiya
Iceberg REST Catalog provides
`/v1/{prefix}/namespaces/{namespace}/tables/{table}/plan`, which pushes scan
planning to the server side.
https://github.com/apache/iceberg/blob/apache-iceberg-1.10.1/open-api/rest-catalog-open-api.yaml#L605-L689
This effort could benefit users.
- Read performance can improve if the catalog effectively caches the response
- Clients can be thin; beneficial for new languages
- With credential vending, we can give more fine-grained credentials
In this ticket, we will try to implement the simplest mode of the server-side
scan planning.
