Redshift user must grant `SELECT` privilege on table [SVV_TABLE_INFO](https://docs.aws.amazon.com/redshift/latest/dg/r_SVV_TABLE_INFO.html) to fetch the metadata of tables and views. For more information visit [here](https://docs.aws.amazon.com/redshift/latest/dg/c_visibility-of-data.html).
- **Username**: Specify the User to connect to Redshift. It should have enough privileges to read all the metadata.
- **Password**: Password to connect to Redshift.
- **Database (Optional)**: 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.
- **Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to Redshift during the connection. These details must be added as Key-Value pairs.
- **Connection Arguments (Optional)**: Enter the details for any additional connection arguments such as security or protocol configs that can be sent to Redshift 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"`
- In case you authenticate with SSO using an external browser popup, then add the `authenticator` details in the Connection Arguments as a Key-Value pair as follows: `"authenticator" : "externalbrowser"`
- **Name**: This field refers to the name of ingestion pipeline, you can customize the name or use the generated name.
- **Database Filter Pattern (Optional)**: Use to database filter patterns to control whether or not to include database as part of metadata ingestion.
- **Include**: Explicitly include databases by adding a list of comma-separated regular expressions to the Include field. OpenMetadata will include all databases with names matching one or more of the supplied regular expressions. All other databases will be excluded.
- **Exclude**: Explicitly exclude databases by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all databases with names matching one or more of the supplied regular expressions. All other databases will be included.
- **Schema Filter Pattern (Optional)**: Use to schema filter patterns to control whether or not to include schemas as part of metadata ingestion.
- **Include**: Explicitly include schemas by adding a list of comma-separated regular expressions to the Include field. OpenMetadata will include all schemas with names matching one or more of the supplied regular expressions. All other schemas will be excluded.
- **Exclude**: Explicitly exclude schemas by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all schemas with names matching one or more of the supplied regular expressions. All other schemas will be included.
- **Table Filter Pattern (Optional)**: Use to table filter patterns to control whether or not to include tables as part of metadata ingestion.
- **Include**: Explicitly include tables by adding a list of comma-separated regular expressions to the Include field. OpenMetadata will include all tables with names matching one or more of the supplied regular expressions. All other tables will be excluded.
- **Exclude**: Explicitly exclude tables by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all tables with names matching one or more of the supplied regular expressions. All other tables will be included.
- **Include views (toggle)**: Set the Include views toggle to control whether or not to include views as part of metadata ingestion.
- **Include tags (toggle)**: Set the Include tags toggle to control whether or not to include tags as part of metadata ingestion.
- **Enable Debug Log (toggle)**: Set the Enable Debug Log toggle to set the default log level to debug, these logs can be viewed later in Airflow.
- **Mark Deleted Tables (toggle)**: This is an optional configuration for enabling soft deletion of tables. When this option is enabled, only tables that have been deleted from the source will be soft deleted, and this will apply solely to the schema that is currently being ingested via the pipeline. Any related entities such as test suites or lineage information that were associated with those tables will also be deleted..
- **Mark All Deleted Tables (toggle)**: This is an optional configuration for enabling soft deletion of tables. When this option is enabled, only tables that have been deleted from the source will be soft deleted, and this will apply to all the schemas available in the data source. Any related entities such as test suites or lineage information that were associated with those tables will also be deleted. Do not enable this option when you have multiple metadata ingestion pipelines. Also make sure to enable the markDeletedTables option for this to work.
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
In order to integrate SSL in the Metadata Ingestion Config, the user will have to add the SSL config under connectionArguments which is placed in the source.
##### **SSL Modes**
There are couple of types of SSL modes that Redshift supports which can be added to ConnectionArguments, they are as follows:
- **disable**: SSL is disabled and the connection is not encrypted.
- **allow**: SSL is used if the server requires it.
- **prefer**: SSL is used if the server supports it. Amazon Redshift supports SSL, so SSL is used when you set sslmode to prefer.
- **require**: SSL is required.
- **verify-ca**: SSL must be used and the server certificate must be verified.
- **verify-full**: SSL must be used. The server certificate must be verified and the server hostname must match the hostname attribute on the certificate.
