Requirements
Metadata: Doris >= 1.2.0, Data Profiler: Doris >= 2.0.2Metadata Ingestion
To ingest metadata from Doris, you need to create a service connection. The service connects Doris with Collate. Once you create a service, Collate automatically starts ingesting metadata.Step 1: Add New Service
- In the left navigation, click Connections.
- On the Connections page, click Add New Service.

Step 2: Select a Service and Connector
From the service type dropdown, select Database Services, then click the Doris 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 Doris services you are ingesting metadata from.
- Optional: Enter a Description for the service.

Note: The service name cannot be changed after it is set.
Step 4: Configure Connection Options
Specify where ingestion runs, provide your source credentials, and verify the connection.Select Ingestion Runner
Select an Ingestion Runner: the runner where the ingestion pipeline will execute.
Enter Connection Details
Enter the connection details for Doris. The right-hand panel in the UI displays inline help for each field.
- Username: Specify the User to connect to Doris. It should have enough privileges to read all the metadata.
- Password: Password to connect to Doris.
- Host and Port: Enter the fully qualified hostname and port number for your Doris deployment in the Host and Port field.
- databaseName: Optional name to give to the database in Collate. If left blank, we will use default as the database name.
- databaseSchema: databaseSchema of the data source. This is optional parameter, if you would like to restrict the metadata reading to a single databaseSchema. When left blank, Collate ingestion attempts to scan all schemas.
- caCertificate: Provide the path to ssl ca file.
- sslCertificate: Provide the path to ssl client certificate file (ssl_cert).
- sslKey: Provide the path to ssl client private key file (ssl_key).
Advanced Configuration
Database Services have an Advanced Configuration section, where you can pass extra arguments to the connector and, if needed, change the connection Scheme. This would only be required to handle 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.
- contains: matches any name containing the value. For example,
salesmatchesmy_sales_dataandsales_2024. - starts with: matches names beginning with the value. For example,
prod_matchesprod_dbandprod_schema. - ends with: matches names ending with the value. For example,
_rawmatchesevents_rawandlogs_raw. - is exactly: matches the exact name only. For example,
analyticsmatches onlyanalytics. - matches regex: matches names using a regular expression. For example,
^prod_.*_v\d+$matchesprod_events_v1.
- Database: Controls which databases Collate ingests from the source.
- Schema: Controls which schemas within the ingested databases are included.
- Table: Controls which tables and views within the ingested schemas are included.
- Stored Procedure: Controls which stored procedures are included in metadata ingestion.
- Scan Mode: You can choose between the following scan modes:
- Scan all: Ingests every asset of that type the connector can access. This is the default.
- Only specific: Enables include rules so only assets matching at least one rule are ingested.
- Exclude system toggle: Use this toggle to automatically filter out system-reserved names defined by the connector — for example, Exclude system databases for the Databases section.
- Always exclude: Add permanent exclusion rules (shown in red). Assets matching these rules are never ingested, regardless of include rules.
- Preview: Shows a real-time summary of what will be in scope based on your current rules.
- Include rules (available only in Only specific mode): Click + Add to define a rule. Added rules appear as chips; an asset is included if it matches any rule.
Step 6: Create & Deploy
Click Create & Deploy to deploy the agent and start the first metadata ingestion run. Collate saves the service configuration and immediately begins pulling metadata from the source. To monitor ingestion progress or view the service you just added, go to Connections in the left navigation and select your service.Configure Metadata Agent and Schedule Ingestion
The Metadata Agent extracts schemas, tables, columns, and other structural metadata from your source and keeps your Collate catalog in sync. It powers discovery, lineage, and governance across your data assets. When you click Create & Deploy, Collate automatically deploys a Metadata Agent for this service and triggers the first ingestion run. View its status and run history from the Agents tab on the service detail page. To configure the additional Metadata Agent and schedule ingestion, follow these steps:- In the left navigation, click Connections and select your service.
- Click the Agents tab.
-
Click Add Agent and select Metadata from the dropdown.
For some services, the dropdown is not available and clicking Add Agent takes you directly to the agent configuration page.
-
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:

-
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:
Note: Available toggles vary by connector. Stored procedure options only appear for connectors that support stored procedures.

-
Advanced Config: Optional connector-specific settings such as Include Views and Extract JSON Schema.

-
Name this Ingestion: Enter a unique recognizable name for this ingestion pipeline.
-
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.

- Click Add to deploy the agent.
Securing Doris Connection with SSL in Collate
To establish secure connections between Collate and Doris, navigate to theAdvanced Config section. Here, you can provide the CA certificate used for SSL validation by specifying the caCertificate. Alternatively, if both client and server require mutual authentication, you’ll need to use all three parameters: ssl_key, ssl_cert, and ssl_ca. In this case, ssl_cert is used for the client’s SSL certificate, ssl_key for the private key associated with the SSL certificate, and ssl_ca for the CA certificate to validate the server’s certificate.
