Huge metadata folders in dbt-trino with Iceberg

[mattiamatrix]

Describe the bug

Hello, I used Elementary with dbt-trino. Elementary tables are stored in S3 as iceberg tables.

Elementary has been running for a while, and the storage keeps growing due to the Iceberg metadata tables, which keep growing.

Trino now supports

write.metadata.delete-after-commit.enabled = true
write.metadata.previous-versions-max = 10

What is the advised approach to maintaining elementary iceberg tables?Should elementary do something, or are users expected to handle it on their own?
