 What's more, the cloud storage access API cost is minimized. 
 Faster and cheaper than direct cloud storage!
 
+SeaweedFS also ships a built-in **Iceberg REST Catalog**, turning the same cluster into a self-contained lakehouse.
+Spark, Trino, Dremio, DuckDB, and RisingWave can query Iceberg tables directly — no Hive Metastore, Glue, or
+external catalog service required. Storage and table metadata live in one system, simplifying on-prem and
+small-team analytics stacks.

+* [Automated table maintenance][IcebergMaintenance]: compaction, snapshot expiration, orphan removal, manifest rewriting.
+* Granular IAM at the bucket, namespace, and table level via standard S3 bucket policies.
