Iceberg Table Format

Question 1

Efficient Table Partitioning

Answer 1

Iceberg automatically optimizes partitioning strategies, which can reduce query costs and improve performance. This avoids traditional static partitioning, which requires you to manually manage and maintain partition keys.

Question 2

Schema Evolution

Answer 2

Iceberg supports schema evolution (e.g., adding, renaming, or removing columns) without needing to rewrite or migrate your data. This can be crucial as your data model changes over time.

Question 3

Time Travel

Answer 3

Time Travel: Iceberg allows you to query historical versions of your table, which means you can “time travel” to see what the data looked like at any previous point in time.

Question 4

ACID Transactions

Answer 4

Iceberg provides support for ACID transactions (Atomicity, Consistency, Isolation, Durability), which is essential for managing concurrent reads and writes. This feature makes it a good fit for environments where data consistency is critical.

Question 5

Compaction and File Management

Answer 5

Iceberg automatically handles small files and compacts them as needed, improving performance and reducing storage costs, especially when dealing with streaming or frequent inserts.
