Core changes for Iceberg + MinIO integration: 1. Docker Compose: Add MinIO service and Iceberg configuration - MinIO for S3-compatible object storage - Iceberg runtime packages for Spark - S3 endpoint and credential configuration 2. Spark Submit: Add Iceberg packages and S3/MinIO configs - iceberg-spark-runtime-3.5_2.12:1.10.0 - hadoop-aws:3.3.4 for S3 filesystem support - Hadoop catalog configuration for Iceberg tables - MinIO S3 endpoint configuration 3. TableUtils: Fix partition detection for Iceberg tables - Disable Hive partition checking (returns empty list) - Treat non-partitioned tables as having all data available - Enables Chronon to process Iceberg tables without partition metadata 4. Build: Enable Spark 3.5 compilation - Set use_spark_3_5 flag for Spark 3.5 compatibility This enables end-to-end data flow: S3/MinIO → Iceberg → Chronon → Iceberg
