Iceberg

The delta destination provides additional features on top of the filesystem destination in OSS dlt. This page only documents the additional features—use the documentation provided in OSS dlt for standard functionality.

Table format​

delta destination automatically assigns delta table format to all resources that it will load. You can still fall back to storing files (as specified in file_format) by setting table_format to native on a resource.

Configuration​

Iceberg destinations looks for its configuration under destination.delta. Otherwise it is configured in the same way as filesystem destination.

[destination.delta]
bucket_url = "s3://[your_bucket_name]" # replace with your bucket name,

[destination.iceberg.credentials]
aws_access_key_id = "please set me up!" # copy the access key here
aws_secret_access_key = "please set me up!" # copy the secret access key here

You are still able to use regular filesystem configuration.

from dlt_plus.destinations import delta

dest_ = delta(destination_name="filesystem")
