Shohei Okumiya commented on HIVE-29599:
---------------------------------------
We may not need to take it so seriously unless Credential Vending is enabled.
If a client has credentials to access the data files, it can read them anyway.
If not, it can't read them anyway. In that case, we just need a feature toggle
to turn in/off `/v1/\{prefix}/namespaces/\{namespace}/tables/\{table}/plan`, or
to configure the security mode.
> 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
> Priority: Major
>
> 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.
