Parameter	Sample Value	Description
S3 Path required	gs://hive-dataproc-generated-bucket/hive-warehouse or s3://<BUCKET_NAME>/	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 Clients required	5	Specifies the number of Hive clients allocated for managing interactions with the Hive Metastore.
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.
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	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.
Catalog Name	olake_iceberg	Name of the Iceberg catalog OLake Go registers tables under. Defaults to olake_iceberg if left empty.
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.
Enable SASL for Hive	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.
Enable Arrow Writes	false/true	Writes data and delete files using Apache Arrow based writer and registers them in Iceberg.
