### Feature Request / Improvement The [GCS Analytics Core](https://github.com/GoogleCloudPlatform/gcs-analytics-core) is a Java library designed to optimize analytics workloads on Google Cloud Storage (GCS). Currently this library includes following optimizations: - Footer Prefetching : At the time of parquet metadata length read, library prefetches fixed size object content from end, this avoids extra network call when backward seek happens to actually read the parquet metadata. - Small object caching : If object is smaller than a threshold(1MB default), read and cache the whole object at once. - threaded VectoredIO implementation: `readVectored` implementation which reads list of ranges in parallel. We are working on the verification of benchmarking numbers for TPCDS and TPCS queries, in micro benchmark using [parquet-java](https://github.com/apache/parquet-java) library this improves parquet metadata parsing by 25+% and parquet file record processing by 15+% on average (for ~2MB, ~30MB, ~300MB, ~3GB randomly generate parquet files). ### Query engine None ### Willingness to contribute - [x] I can contribute this improvement/feature independently - [x] I would be willing to contribute this improvement/feature with guidance from the Iceberg community - [ ] I cannot contribute this improvement/feature at this time -- This is an automated message from the Apache Git Service.
