Description
Adds manifest file caching to the Iceberg connector for HMS-based deployments.
Motivation and Context
In order to optimize and plan iceberg queries we call the
planFiles()
API multiple times throughout the query optimization lifecycle. Each time it requires reading and parsing metadata files which usually exist on an external filesystem such as S3. For large tables there could be hundreds of files. They usually range in a few kilobytes in size up to a few megabytes. When not cached in memory within Presto it can lead to significant E2E query latency degradation.Impact
