Databricks Lakehouse

Overview

This destination syncs data to Delta Lake on Databricks Lakehouse. Each stream is written to its own delta-table.

caution

You must be using Unity Catalog to use this connector.

This connector requires a JDBC driver to connect to the Databricks cluster. By using the driver and the connector, you must agree to the JDBC ODBC driver license. This means that you can only use this connector to connect third party applications to Apache Spark SQL within a Databricks offering using the ODBC and/or JDBC protocols.

Airbyte Setup

When setting up a Databricks destination, you need these pieces of information:

Server Hostname / HTTP Path / Port

  1. Open the workspace console.

  2. Open your SQL warehouse:

  3. Open the Connection Details tab:

  4. Finally, you'll need to provide the Databricks Unity Catalog Path, which is the path to the database you wish to use within the Unity Catalog. This is often the same as the workspace name.

Authentication

Follow the instructions in Databricks documentation to generate a client ID and secret.

  1. Open your workspace console.

  2. Click on your icon in the top-right corner, and head to settings, then developer, then manage under access tokens

  3. Enter a description for the token and how long it will be valid for (or leave blank for a permanent token):

Other Options

  • Default Schema - The schema that will contain your data. You can later override this on a per-connection basis.
  • Purge Staging Files and Tables - Whether Airbyte should delete files after loading them into tables. Note: if deselected, Databricks will still delete your files after your retention period has passed (default - 7 days).

Sync Mode

FeatureSupportNotes
Full Refresh SyncWarning: this mode deletes all previously synced data in the configured bucket path.
Incremental - Append Sync
Incremental - Append + Deduped
Namespaces

Output Schema

Each table will have the following columns, in addition to your whatever columns were in your data:

ColumnTypeNotes
_airbyte_raw_idstringA random UUID.
_airbyte_extracted_attimestampTimestamp when the source read the record.
_airbyte_loaded_attimestampTimestamp when the record was written to the destination
_airbyte_generation_idbigintSee the refreshes documentation.

Airbyte will also produce "raw tables" (by default in the airbyte_internal schema). We do not recommend directly interacting with the raw tables, and their format is subject to change without notice.
