Dear Gobblin maintainers, Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below! ### JIRA - [x] My PR addresses the following [Gobblin JIRA](https://issues.apache.org/jira/browse/GOBBLIN/) issues and references them in the PR title. For example, "[GOBBLIN-XXX] My Gobblin PR" - https://issues.apache.org/jira/browse/GOBBLIN-2231 ### Description - [x] Here are some details about my PR, including screenshots (if applicable): - This PR introduces IcebergFileStreamExtractor, enabling partition-aware file-level streaming from Iceberg tables to any destination (e.g., Azure, S3, HDFS). This is a follow-up PR to the IcebergSource and IcebergFileStreamHelper implementation - https://github.com/apache/gobblin/pull/4146. **Additions** - Added IcebergFileStreamExtractor extending FileBasedExtractor. - Implemented partition-aware destination path computation for date-partitioned Iceberg tables. - Integrated with IcebergSource to consume partition metadata from work units. - Builds CopyableFile with both source and destination metadata. **Behavior** - Reads partition → path mapping from the work unit. - Computes destination paths while preserving partition structure: - Partitioned tables: `<finalDir>/<partitionPath>/<filename>` ``` Example: /data/table1/datepartition=2025-04-01-00/file.parquet ``` Non-partitioned tables: `<finalDir>/<filename>` ### Tests - [x] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason: ### Commits - [x] My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue.
