# Lakehouse connector

The Lakehouse connector combines the features of the
[Hive](/connector/hive), [Iceberg](/connector/iceberg),
[Delta Lake](/connector/delta-lake), and [Hudi](/connector/hudi)
connectors into a single connector. It allows you to query or write
to data stored in multiple table types (also known as table formats)
that all share the same file system and metastore service.

## General configuration

To configure the Lakehouse connector, create a catalog properties file
`etc/catalog/example.properties` with the following content, replacing the
properties as appropriate:

```text
connector.name=lakehouse
```

You must configure a [metastore for metadata](/object-storage/metastores).
The `hive.metastore` property will also configure the Iceberg catalog.
Do not specify `iceberg.catalog.type`.

You must select and configure one of the
[supported file systems](lakehouse-file-system-configuration).

## Configuration properties

The following configuration properties are available:

:::{list-table}
:widths: 30, 58, 12
:header-rows: 1

* - Property name
- Description
- Default
* - `lakehouse.table-type`
- The default table type for newly created tables when the `format`
table property is not specified. Possible values:
* `HIVE`
* `ICEBERG`
* `DELTA`
- `ICEBERG`
:::

(lakehouse-file-system-configuration)=
## File system access configuration

The connector supports accessing the following file systems:

* [](/object-storage/file-system-azure)
* [](/object-storage/file-system-gcs)
* [](/object-storage/file-system-s3)
* [](/object-storage/file-system-hdfs)

We don't have that for other connectors. Should we?


You must enable and configure the specific file system access.

## Examples

Create an Iceberg table:

```sql
CREATE TABLE iceberg_table (
c1 INTEGER,
c2 DATE,
c3 DOUBLE
)
WITH (
type = 'ICEBERG'
format = 'PARQUET',
partitioning = ARRAY['c1', 'c2'],
sorted_by = ARRAY['c3']
);
```

Create a Hive table:

```sql
CREATE TABLE hive_page_views (
view_time TIMESTAMP,
user_id BIGINT,
page_url VARCHAR,
ds DATE,
country VARCHAR
)
WITH (
type = 'HIVE',
format = 'ORC',
partitioned_by = ARRAY['ds', 'country'],
bucketed_by = ARRAY['user_id'],
bucket_count = 50
)
```
