Parameter	Sample Value	Description
iceberg_s3_path required	s3://warehouse/ or gs://hive-dataproc-generated-bucket/hive-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.
hive_uri required	thrift://<hostname>:9083 or thrift://METASTORE_IP:9083	Thrift endpoint URL for your Hive Metastore service. OLake Go uses this to read and write Iceberg catalog metadata.
hive_clients required	5	Specifies the number of Hive clients allocated for managing interactions with the Hive Metastore.
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.
s3_endpoint	http://S3_ENDPOINT	S3 API endpoint for writing Iceberg data files. Optional for AWS S3 but required for S3-compatible storage like MinIO.
catalog_name	olake_iceberg	Name of the Iceberg catalog OLake Go registers tables under. Defaults to olake_iceberg if left empty.
s3_use_ssl	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).
s3_path_style	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.
hive_sasl_enabled	false/true	Enables SASL authentication when OLake Go connects to the Hive Metastore over Thrift. Required only if your metastore enforces SASL-based client authentication.
arrow_writes	false/true	Writes data and delete files using Apache Arrow based writer and registers them in Iceberg.
