Apache Iceberg: Revolutionizing Geospatial Data Lakes
Apache Iceberg, an open table format, now supports geometry data columns, a game-changer for geospatial data users. Traditional methods struggle with datasets exceeding a million features, but Iceberg, built on Parquet, offers blazing-fast reads and scalability for massive datasets. It provides developer-friendly features like DML operations (insert, update, merge, delete), versioning, and time travel, addressing data lake limitations like unreliable transactions and concurrency issues. Iceberg supports geospatial delete operations, time travel, and upserts, along with schema enforcement, evolution, efficient file listing, and small file compaction. Its merge-on-read capability drastically improves DML performance. Iceberg offers a superior alternative to traditional geospatial data handling, significantly improving performance and reliability.
