### Step 2: Select a Service and Connector
From the service type dropdown, select **Database Services**, then click the **AzureSQL** connector tile.
### Step 3: Add Service Name and Description
* Enter a unique, descriptive **Service Name**. Collate identifies services by their service name. Enter a name that distinguishes this deployment from other AzureSQL services you are ingesting metadata from.
* Optional: Enter a **Description** for the service.
#### Enter Connection Details
Enter the connection details for AzureSQL. The right-hand panel in the UI displays inline help for each field.
* **Username**: Specify the user to connect to AzureSQL. It should have enough privileges to read all the metadata.
* **Password**: Password to connect to AzureSQL.
* **Host and Port**: Enter the fully qualified hostname and port number for your AzureSQL deployment in the Host and Port field.
* **Database**: Optional. Restrict metadata reading to a single database. If left blank, Collate scans all databases.
* **Driver**: Connecting to AzureSQL requires an ODBC driver. Specify the ODBC driver name in the field. Download the [ODBC driver for SQL Server](https://learn.microsoft.com/en-us/sql/connect/odbc/download-odbc-driver-for-sql-server?view=sql-server-ver16). Docker and Kubernetes deployments include this driver by default (`ODBC Driver 18 for SQL Server`).
#### Authentication Mode
* **Authentication**:
* The `authentication` parameter determines the method of authentication when connecting to AzureSQL using ODBC (Open Database Connectivity).
* If you select **"Active Directory Password"**, you'll need to provide the password associated with your Azure Active Directory account.
* Alternatively, if you choose **"Active Directory Integrated"**, the connection uses the credentials of the currently logged-in user. This mode ensures secure and seamless connections with AzureSQL.
* **Encrypt**:
* The `encrypt` setting in the connection string pertains to data encryption during communication with AzureSQL.
* When enabled, it ensures that data exchanged between your application and the database is encrypted, enhancing security.
* **Trust Server Certificate**:
* The `trustServerCertificate` option also relates to security.
* When set to true, your application trusts the server's SSL certificate without validation. Use this cautiously, as it bypasses certificate validation checks.
* **Connection Timeout**:
* The `connectionTimeout` parameter specifies the maximum time, in seconds, that your application waits while attempting to establish a connection to AzureSQL.
* If Collate cannot establish the connection within this timeframe, it raises an error.
#### Advanced Configuration
Database Services include an Advanced Configuration section for passing extra arguments to the connector and, if needed, changing the connection scheme. Use these fields only for advanced connectivity scenarios or customizations.
* **Connection Options (Optional)**: Enter the details for any additional connection options that can be sent to database 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 during the connection. These details must be added as Key-Value pairs.
#### Test Connection
Once the credentials have been added, click on **Test Connection** and **Save** the changes.
### Step 5: Configure Ingestion Options
In the **What to Ingest** step, use filter patterns to control which assets Collate ingests from your database service. Filter patterns use regular expressions applied to asset names.
#### How Filter Patterns Work
* **Include**: Add one or more comma-separated regular expressions. Collate ingests only assets whose names match at least one expression. Leave blank to include all assets.
* **Exclude**: Add one or more comma-separated regular expressions. Collate skips any asset whose name matches an expression. Leave blank to exclude nothing.
Rules match asset names using one of five expressions:
* **contains**: matches any name containing the value. For example, `sales` matches `my_sales_data` and `sales_2024`.
* **starts with**: matches names beginning with the value. For example, `prod_` matches `prod_db` and `prod_schema`.
* **ends with**: matches names ending with the value. For example, `_raw` matches `events_raw` and `logs_raw`.
* **is exactly**: matches the exact name only. For example, `analytics` matches only `analytics`.
* **matches regex**: matches names using a regular expression. For example, `^prod_.*_v\d+$` matches `prod_events_v1`.
When both Include and Exclude are set, Exclude takes priority.
For some services, the dropdown is not available and clicking **Add Agent** takes you directly to the agent configuration page.
4. On the **Configure Ingestion** page, do the following and click **Next**.
* **Name this Ingestion**: Enter a unique recognizable name for this ingestion pipeline.
* **Agent Setup**: Configure core parameters for metadata extraction. The following fields are available:
| Field | Default | Description |
| ------------------------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------ |
| Default Owner | — | Owner applied to all entities when no specific level owner is configured. Accepts a user or team name/email. |
| Service Owner | — | Owner assigned to the service entity. |
| Database Owner | — | Owner assigned to all ingested databases. Accepts a single owner or a per-database name mapping. |
| Database Schema Owner | — | Owner assigned to all ingested schemas. Accepts a single owner or a per-schema name mapping. |
| Table Owner | — | Owner assigned to all ingested tables. Accepts a single owner or a per-table name mapping. |
| Enable Inheritance | On | When on, child entities inherit the owner from their parent when they have no owner configured. |
| Query Log Duration | 1 | Number of days to look back in query logs when processing stored procedure results. |
| Query Parsing Timeout Limit | 300 | Timeout in seconds for parsing a single query. |
| Number of Threads | 1 | Number of threads to use for parallel table ingestion. |
| Incremental Extraction | Off | When enabled, subsequent runs only extract entities changed since the last successful run. |
| Successful Pipeline Run Lookback Days | 7 | Number of days to search back for a prior successful run to use as a baseline for incremental extraction. |
| Safety Margin Days | 1 | Additional days added to the baseline timestamp as a buffer for incremental extraction. |
| JSON Schema Sample Size | 10 | Number of rows sampled to infer JSON column schema. Only applies when Extract JSON Schema is enabled in Advanced Config. |
* **Filter Patterns**: Apply include or exclude rules to scope which databases, schemas, tables, and stored procedures this agent ingests. For more information about various filter options, see **Step 5: Configure Ingestion Options**.
* **Scope & Behaviour**: Control how the agent handles metadata during ingestion. Toggle each option on or off based on your needs:
| Toggle | Default | Description |
| ------------------------------ | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Include Tables | On | Ingest table metadata from the source. Turn off to skip tables entirely. |
| Include Tags | On | Ingest tags from the source. |
| Include Stored Procedures | On | Ingest stored procedure metadata. |
| Include DDL Statements | Off | Ingest DDL statements alongside table metadata. |
| Include Owners | Off | Assign owners to ingested entities when the source owner's email matches a user in Collate. Does not overwrite an existing owner. |
| Include Custom Properties | Off | Ingest connector-specific custom properties onto entities. |
| Mark Deleted Tables | On | Soft-delete tables in Collate when they are removed from the source. Applies only within the currently ingested schema. |
| Mark Deleted Stored Procedures | On | Soft-delete stored procedures in Collate when they are removed from the source. |
| Mark Deleted Schemas | Off | Soft-delete schemas and all their child assets when removed from the source. |
| Mark Deleted Databases | Off | Soft-delete databases and all their child assets when removed from the source. |
| Override Metadata | Off | When on, source values overwrite existing descriptions, tags, owners, and display names in Collate. When off, Collate only updates fields that have no existing value. |
| Enable Debug Log | Off | Sets the ingestion log level to DEBUG. Useful for troubleshooting. |
* **Advanced Config**: Optional connector-specific settings such as Include Views and Extract JSON Schema.
5. On the **Schedule Interval** page, set when the agent runs:
* **Schedule**: Choose a preset interval (Hourly, Daily, Weekly, Monthly) or enter a custom cron expression.
* **On-Demand**: No automatic schedule; trigger the agent manually when needed.
6. Click **Add** to deploy the agent.
