Summary: Optimize Iceberg metadata handling
Key: IMPALA-10737
URL: https://issues.apache.org/jira/browse/IMPALA-10737
Project: IMPALA
Issue Type: Bug
Components: Frontend
Reporter: Zoltán Borók-Nagy
Currently we re-read Iceberg table metadata in several cases.
We should rather keep it in memory and use it when possible.
Also, when refreshing a table we should use Iceberg's refresh() API to avoid
unnecessary re-reads of manifest files:
