| <h2>What is Iceberg?</h2> |
| <br /> |
| |
| <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. |

| <h2 class="section-heading">Expressive SQL</h2> |
| <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. |

| <h2 class="section-heading">Hidden Partitioning</h2> |
| <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. |
