Introduces a Hive metastore catalog integration for managing Iceberg data lakes within ClickHouse.
Why it matters
This feature enables ClickHouse to interact with Iceberg tables using the Hive metastore catalog, allowing users to seamlessly query and manage large-scale Iceberg datasets. It solves the problem of catalog compatibility and simplifies data lake management by leveraging the widely used Hive metastore for Iceberg table metadata storage.How to use it
To use this feature, configure ClickHouse to connect to the Hive metastore by setting up a Hive catalog that points to the Iceberg data lake. Once the catalog is configured, queries can be executed directly on Iceberg tables through ClickHouse using standard SQL syntax.
