Apache Iceberg

Apache Iceberg is a format for huge analytic tables designed to address some of the scaling issues with traditional Hive tables. Iceberg depends on a Hive metastore being present and makes use of the same metastore ConfigMap used by the Hive connector.

You can deploy a Hive Metastore Stacklet with the Stackable Operator for Apache Hive.

Example Iceberg catalog configuration

apiVersion: trino.stackable.tech/v1alpha1
kind: TrinoCatalog
metadata:
  name: iceberg  (1)
  labels:
    trino: simple-trino
spec:
  connector:
    # Specify iceberg here when defining a iceberg catalog
    iceberg:
      metastore:
        configMap: simple-hive  (2)
      s3:
        inline:
          host: test-minio
          port: 9000
          accessStyle: Path
          credentials:
            secretClass: minio-credentials

1	The name of the catalog as it will appear in Trino
2	This is the name of your Hive Stacklet

Connect to S3 store or HDFS

The Iceberg connector can connect to S3 or HDFS in the same way the Apache Hive connector does. Please check that documentation on how to configure the access.
