Parameter	Sample Value	Description
JDBC URL required	jdbc:postgresql://<DB_URL>:5432/iceberg	JDBC connection string for the catalog database. Replace <DB_URL> with your database host or use host.docker.internal for local Docker containers.
JDBC Username required	iceberg	Database username for JDBC catalog authentication.
JDBC Password required	password	Database password for JDBC catalog authentication.
S3 Path required	s3://warehouse	S3 bucket path where Iceberg table data and metadata files will be stored.
AWS Region required	us-east-1	AWS Region where your S3 bucket exist. Required so OLake Go calls the correct regional S3 endpoints.
Catalog Name	olake_iceberg	Name of the Iceberg catalog OLake Go registers tables under. Defaults to olake_iceberg if left empty.
S3 Endpoint	https://glue.ap-south-1.amazonaws.com	S3 API endpoint for writing Iceberg data files. Optional for AWS S3 but required for S3-compatible storage like MinIO.
Use SSL for S3	false/true	Controls whether OLake Go uses HTTPS when connecting to the S3 API for writing Iceberg files. Set to false when S3 Endpoint uses http:// (for example, local MinIO). Set to true when the endpoint uses https:// (for example, AWS S3 or TLS-enabled MinIO).
Use Path Style for S3	false/true	Controls how OLake Go formats S3 request URLs. Path-style puts the bucket name in the URL path instead of the hostname. This is required for MinIO and other S3-compatible storage that do not support AWS-style virtual-hosted URLs.
AWS Access Key	XXX	AWS access key ID for authentication. Optional if using IAM roles or instance profiles. If using IAM: Docker Compose: add the required IAM environment variables under x-envs in your compose file. See Service Environment Variables for setup details. Kubernetes: set up pod IAM in Cloud IAM Integration.
AWS Secret Key	XXX	AWS secret access key for authentication. Optional if using IAM roles or instance profiles. If using IAM: Docker Compose: add the required IAM environment variables under x-envs in your compose file. See Service Environment Variables for setup details. Kubernetes: set up pod IAM in Cloud IAM Integration.
Enable Arrow Writes	false/true	Writes data and delete files using Apache Arrow based writer and registers them in Iceberg.
