Redshift data sources

  • Redshift Spectrum data sources must be registered using .

  • Registering Redshift datashares as Immuta data sources is unsupported.

Requirement

The must be set to false (default setting) for your Redshift cluster.

Enter connection information

  1. Navigate to the Data Sources list page and click Register Data Source.

  2. Select the Redshift tile in the Data Platform section.

  3. Complete these fields in the Connection Information box:

    • Server: hostname or IP address

    • Port: port configured for Redshift, typically port 5439

    • SSL: when enabled, ensures communication between Immuta and the remote database is encrypted

    • Database: the remote database

    • Username: the username to use to connect to the remote database and retrieve records for this data source

    • Password: the password to use with the above username to connect to the remote database

  4. You can then choose to enter Additional Connection String Options or Upload Certificates to connect to the database.

  5. Click the Test Connection button.

Use SSL

Although not required, it is recommended that all connections use SSL. Additional connection string arguments may also be provided.

Note: Only Immuta uses the connection you provide and injects all policy controls when users query the system. In other words, users always connect through Immuta with policies enforced and have no direct association with this connection.

Further considerations

  • Immuta pushes down joins to be processed on the remote database when possible. To ensure this happens, make sure the connection information matches between data sources, including host, port, ssl, username, and password. You will see performance degradation on joins against the same database if this information doesn't match.

  • If a client certificate is required to connect to the source database, you can add it in the Upload Certificates section.

Select virtual population

Decide how to virtually populate the data source by selecting one of the options:

  • Create sources for all tables in this database: This option will create data sources and keep them in sync for every table in the dataset. New tables will be automatically detected and new Immuta views will be created.

  • Schema / Table: This option will allow you to specify tables or datasets that you want Immuta to register.

    1. Opt to Edit in the table selection box that appears.

    2. By default, all schemas and tables are selected. Select and deselect by clicking the checkbox for the schemas in the Import Schemas/Tables modal. You can create multiple data sources at one time by selecting an entire schema or multiple tables.

    3. After making your selection(s), click Apply.

Enter basic information

  1. Enter the SQL Schema Name Format to be the SQL name that the data source exists under in Immuta. It must include a schema macro but you may personalize it using lowercase letters, numbers, and underscores to personalize the format. It may have up to 255 characters.

  2. Enter the Schema Project Name Format to be the name of the schema project in the Immuta UI. If you enter a name that already exists, the name will automatically be incremented. For example, if the schema project Customer table already exists and you enter that name in this field, the name for this second schema project will automatically become Customer table 2 when you create it.

    1. When selecting Create sources for all tables in this database and monitor for changes you may personalize this field as you wish, but it must include a schema macro.

    2. When selecting Schema/Table this field is prepopulated with the recommended project name and you can edit freely.

  3. Select the Data Source Name Format, which will be the format of the name of the data source in the Immuta UI.

    • <Tablename>: The data source name will be the name of the remote table, and the case of the data source name will match the case of the macro.

    • <Schema><Tablename>: The data source name will be the name of the remote schema followed by the name of the remote table, and the case of the data source name will match the cases of the macros.

    • Custom: Enter a custom template for the Data Source Name. You may personalize this field as you wish, but it must include a tablename macro. The case of the macro will apply to the data source name (i.e., <Tablename> will result in "Data Source Name," <tablename> will result in "data source name," and <TABLENAME> will result in "DATA SOURCE NAME").

  4. Enter the SQL Table Name Format, which will be the format of the name of the table in Immuta. It must include a table name macro, but you may personalize the format using lowercase letters, numbers, and underscores. It may have up to 255 characters.

Schema monitoring best practices

Schema monitoring is a powerful tool that ensures tables are all governed by Immuta.

  • Consider using schema monitoring later in your onboarding process, not during your initial setup and configuration when tables are not in a stable state.

Note: This step will only appear if all tables within a server have been selected for creation.

Opt to configure advanced settings

Although not required, completing these steps will help maximize the utility of your data source. Otherwise, click Create to save the data source.

Column detection

This setting monitors when remote tables' columns have been changed, updates the corresponding data sources in Immuta, and notifies Data Owners of these changes.

To enable, select the checkbox in this section.

Event time

An Event Time column denotes the time associated with records returned from this data source. For example, if your data source contains news articles, the time that the article was published would be an appropriate Event Time column.

  1. Click the Edit button in the Event Time section.

  2. Select the column(s).

  3. Click Apply.

Selecting an Event Time column will enable

  • more statistics to be calculated for this data source including the most recent record time, which is used for determining the freshness of the data source.

  • the creation of time-based restrictions in the policy builder.

Latency

  1. Click Edit in the Latency section.

  2. Complete the Set Time field, and then select MINUTES, HOURS, or DAYS from the subsequent dropdown menu.

  3. Click Apply.

This setting impacts how often Immuta checks for new values in a column that is driving row-level redaction policies. For example, if you are redacting rows based on a country column in the data, and you add a new country, it will not be seen by the Immuta policy until this period expires.

Sensitive data discovery

Data owners can disable sensitive data discovery for their data sources in this section.

  1. Click Edit in this section.

  2. Select Enabled or Disabled in the window that appears, and then click Apply.

Data source tags

Adding tags to your data source allows users to search for the data source using the tags and Governors to apply Global policies to the data source. Note if Schema Detection is enabled, any tags added now will also be added to the tables that are detected.

To add tags,

  1. Click the Edit button in the Data Source Tags section.

  2. Begin typing in the Search by Tag Name box to select your tag, and then click Add.

Tags can also be added after you create your data source from the data source details page on the overview tab or the data dictionary tab.

Create the data source

Click Create to save the data source(s).

Consider using to either run the schema monitoring job when your ETL process adds new tables or to add new tables.

Activate the to protect potentially sensitive data. This policy will null the new columns until a data owner reviews new columns that have been added, protecting your data to avoid data leaks on new columns getting added without being reviewed first.

When selecting the Schema/Table option, you can opt to enable by selecting the checkbox in this section.

See the page to learn more about column detection.
