<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. |

<p> |
|

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. |

<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. |

Time-travel enables reproducible queries that use exactly the same |

rollback allows users to quickly correct problems by resetting |
