About the Connections page
- View and manage the responsibilities of users and user groups on each data source.
- Link the results of Data Quality Jobs that run on a given connection to related System assets in Data Catalog.
- Edit the details of a JDBC connection on the Edge site.
- Quickly access the Edge site.
Overview of the Connections page user interface
The following image and sections describe the key functional areas of the Connections page.
Connections list
The Connections list (
) shows the name of the data quality connection between the Edge site and a data source. You can filter this list using the search bar.
Edge details
The Edge details (
) section provides configuration information about your connection. It includes:
- Edge connection: The name of the JDBC connection to the Edge site. You can click the link to edit the connection details.
- Edge site: The name of the Edge site. You can click the link to open the Edge site and manage it as needed.
- Capability: The specific type of processing capability that your Edge connection uses. This field is not editable and is either Pushdown or Pullup depending on the data quality capability that your connection uses.
Find related assets
This section (
) allows you to link the results of jobs to related System assets in Data Catalog. You have two options for linking a connection to a System asset:
There are two options for linking a connection to a System asset:
- Use Edge connection name: This option allows Collibra to use the name of the Edge connection to link to a related System asset of the same name in Data Catalog. For example, in the screenshot above, this option links to a System asset in Data Catalog called "DQ_SNOWFLAKE_PUSHDOWN".
- Specify a system in Catalog: This option allows you to select an existing System asset in Data Catalog. Use this option when the Edge connection name does not match a related System asset in Data Catalog or when you need separate Edge connections for data quality and ingestion.
Responsibilities
The responsibilities section (
) shows the users and user groups added to out-of-the-box and custom resource roles. These resource roles allow your colleagues to perform various actions on jobs created on the connection.
For example, the Data Quality Manager and Data Quality Editor out-of-the-box resource roles allow users added to them to perform the actions permitted by those roles. A user added to the DQ_JOB_RUN custom role can perform the actions granted when you created that role.
Click Add to the right of the responsibilities section to open the Add responsibility dialog box. From there, you can add custom responsibilities to your connection.
Manage cache
The Manage cache section (
) allows you to view when the system last updated the metadata, or click 
to schedule an immediate cache refresh.
The Monitoring Overview page uses persistent caching to store metadata in the database using lazy loading. This means the system caches entries only for items you actually interact with, such as connections, databases, schemas, tables, and columns.
The system caches the following metadata:
- List of databases
- List of schemas
- List of tables
- List of columns
A background refresh process keeps cached metadata up to date. It runs on a configurable schedule (every 24 hours by default), checks for expired entries, and refreshes them from the Edge Session Manager. If a refresh succeeds, the system replaces the cached value and updates its timestamps. If a refresh fails, the system keeps the existing cached value.
You can view when the system last updated the metadata, or click the refresh icon to schedule an immediate cache refresh.
