Configure PostgreSQL with Zing
Set Up a Data Source
Zing is built to query your own data, so you’ll want to set up a data source. While we provide a sample data set to help you get situated, adding your own data source (or sources) will make it possible to start asking questions of your company’s data from your phone or the web.
Adding a Data Source
The easiest way to set up a dataset is from the Zing web console,
- Once you are logged in, tap data sources then the new data source button.
- In the modal, select the data source type (such as Postgres, BigQuery, etc.)
- Enter your database credentials, such as hostname, port, database name, username, and password
- Press save
- Zing will validate that your database credentials are valid once you press save and will add the source. It is then available immediately to query. If your credentials are invalid you’ll be prompted to check and resubmit.
You can also add database credentials directly from the Zing web, iOS, and Android apps by tapping the sources tab in the mobile app, then add new data source and following the steps above.
Once a data source as been added, it will immediately be available to all users that you have invited to your organization in the top of their Zing app in the tables section.
Note: You can set up multiple data sources with an organization, even across data source types. Zing will show the tables and views across data sources in the app.
Supported Data Sources
|PostgreSQL||Yes||Zing also supports cloud-hosted versions of this such as Amazon RDS and Google Cloud SQL|
|Google BigQuery||Yes||Setup only via web app (not mobile app)|
|Trino / Presto / Starburst||Yes|
|Microsoft SQL Server||Yes||Setup only via web app|
|Azure SQL||Yes||Setup only via web app|
|Databricks||Yes||Setup only via web app|
Choosing what tables and views are visible
By default, all tables and views in your database are marked as ‘visible’ (including newly added tables), but you can exclude tables or views from visible and queryable in Zing if you’d like.
This is useful for excluding tables from other people in your organization which might be unnecessary for them (e.g. detailed server logs), or in simplifying the set of tables shown in Zing to be more streamlined.
To turn off tables or views:
First connect to your data source.
Then you’ll see a ’tables’ list and you can turn on/off all or individual tables/views.
Data Source Security
Two things you should to to ensure your database’s connection to Zing is secure:
Security best practices are to provide Zing read-only access (instead of full access) to your database. Zing doesn’t need write permissions and best security protocols dictate minimizing permissions. You see how to do this on StackOverflow for Postgres and mySQL.
When you make a data source accessible to the internet for Zing to be able to connect, it is best practice to limit the IP addresses that your database server will respond to.
This ensures that other IP addresses cannot access your database and only authorized IPs (such as Zing) are able to do so.
Zing’s IP address to whitelist is: 184.108.40.206
Additionally, if your database supports SSL, you should turn that on.
