          <p>
            Iceberg is a high-performance format for huge analytic tables. Iceberg
            brings the reliability and simplicity of SQL tables to big data, while
            making it possible for engines like Spark, Trino, Flink, Presto, Hive
            and Impala to safely work with the same tables, at the same time.

            <p>
              Iceberg supports flexible SQL commands to merge new data, update
              existing rows, and perform targeted deletes. Iceberg can eagerly
              rewrite data files for read performance, or it can use delete deltas
              for faster updates.

              Schema evolution just works. Adding a column won't bring back
              "zombie" data. Columns can be renamed and reordered. Best of all,
              schema changes never require rewriting your table.

            <p>
              Iceberg handles the tedious and error-prone task of producing
              partition values for rows in a table and skips unnecessary
              partitions and files automatically. No extra filters are needed for
              fast queries, and table layout can be updated as data or queries
              change.
