In this section, we provide guides and references to use the Redshift connector.

Configure and schedule Redshift metadata and profiler workflows from the OpenMetadata UI:

{% partial file="/v1.3/connectors/external-ingestion-deployment.md" /%}

Requirements

{%inlineCallout icon="description" bold="OpenMetadata 0.12 or later" href="/deployment"%} To deploy OpenMetadata, check the Deployment guides. {%/inlineCallout%}

Redshift user must grant SELECT privilege on table SVV_TABLE_INFO to fetch the metadata of tables and views. For more information visit here.


CREATE USER test_user with PASSWORD 'password';
GRANT SELECT ON TABLE svv_table_info to test_user;

Python Requirements

To run the Redshift ingestion, you will need to install:

pip3 install "openmetadata-ingestion[redshift]"

If you want to run the Usage Connector, you'll also need to install:

pip3 install "openmetadata-ingestion[redshift-usage]"

Metadata Ingestion

All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to Redshift.

In order to create and run a Metadata Ingestion workflow, we will follow the steps to create a YAML configuration able to connect to the source, process the Entities if needed, and reach the OpenMetadata server.

The workflow is modeled around the following JSON Schema

Note: During the metadata ingestion for redshift, the tables in which the distribution style i.e DISTSTYLE is not AUTO will be marked as partitioned tables

1. Define the YAML Config

This is a sample config for Redshift:

{% codePreview %}

{% codeInfoContainer %}

Source Configuration - Service Connection

{% codeInfo srNumber=1 %}

username: Specify the User to connect to Snoflake. It should have enough privileges to read all the metadata.

{% /codeInfo %}

{% codeInfo srNumber=2 %}

password: Password to connect to Redshift.

{% /codeInfo %}

{% codeInfo srNumber=3 %}

database: The database of the data source is an optional parameter, if you would like to restrict the metadata reading to a single database. If left blank, OpenMetadata ingestion attempts to scan all the databases.

{% /codeInfo %}

{% codeInfo srNumber=4 %}

hostPort: Host and port of the Redshift service.

{% /codeInfo %}

{% codeInfo srNumber=5 %}

ingestAllDatabases: Ingest data from all databases in Redshift. You can use databaseFilterPattern on top of this.

{% /codeInfo %}

{% partial file="/v1.3/connectors/yaml/database/source-config-def.md" /%}

{% partial file="/v1.3/connectors/yaml/ingestion-sink-def.md" /%}

{% partial file="/v1.3/connectors/yaml/workflow-config-def.md" /%}

Advanced Configuration

{% codeInfo srNumber=6 %}

Connection Options (Optional): Enter the details for any additional connection options that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

{% /codeInfo %}

{% codeInfo srNumber=7 %}

Connection Arguments (Optional): Enter the details for any additional connection arguments such as security or protocol configs that can be sent to Athena during the connection. These details must be added as Key-Value pairs.

  • In case you are using Single-Sign-On (SSO) for authentication, add the authenticator details in the Connection Arguments as a Key-Value pair as follows: "authenticator" : "sso_login_url"
