The record

Purpose: AetherLake is a Kubernetes-native data lakehouse that combines storage, catalog, federated SQL, stream processing, orchestration, BI, and identity in a web control panel.
Components: Its listed components include MinIO, Trino, Apache Polaris, Kafka, Flink, dbt, Airflow, Superset, Spark, Milvus, Prometheus, Grafana, PostgreSQL, and Keycloak.
Control panel: The control panel shows pod health and resource use, supports service restarts, and includes workspaces for dbt, Kafka, Flink SQL, Trino queries, and Iceberg catalogs.
Data transformations: Its dbt examples describe Bronze, Silver, and Gold stages using Kafka, Flink, Parquet, Iceberg, Superset, and Trino.
Streaming: Kafka and Flink are enabled by default, and the project describes streaming Kafka data into Iceberg tables and querying Kafka topics through Trino.
Identity: Keycloak provides OIDC single sign-on across services, with role names data-admin, data-scientist, and data-engineer.
Security: The project says credentials are randomly generated per installation and advises setting production secrets and real TLS certificates before exposing a cluster.
Telemetry: An anonymous heartbeat tracks installation counts, detected cloud environments, and component health; the project says it excludes PII, schemas, and dataset contents and can be disabled.
Deployment: The quick start lists Kubernetes, Helm 3.12 or later, kubectl, Docker, and an NGINX ingress controller as prerequisites.
Cloud support: The repository describes deployment configurations for AWS, Azure, and Google Cloud Platform.
AI integrations: The MCP server lets AI assistants such as Claude and Cursor access platform status, logs and restarts, Trino queries, Polaris catalogs, and Airflow DAGs.
License: The repository states BUSL-1.1 permits internal use, modification, and self-hosting; commercial hosted or managed offerings require a license, and releases convert to Apache-2.0 after four years.
Languages: The control panel is described as bilingual in English and Turkish.
Data stack: Its listed components include MinIO, Trino, Apache Polaris, Kafka, Flink, dbt, Airflow, Superset, Spark, and Milvus.
