Metadata Ingestion

​

Step 1: Add New Service

1. In the left navigation, click Connections.
2. On the Connections page, click Add New Service.

​

Step 2: Select a Service and Connector

​

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.

​

Step 4: Configure Connection Options

​

Select Ingestion Runner

​

Enter Connection Details

• 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. 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

• 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

Step 5: Configure Ingestion Options

​

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, 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.

​

Filter Options

• 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: 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 Collate ingests only assets that match at least one rule.
• 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). Collate never ingests assets matching these rules, regardless of include rules.
• Preview: Shows a real-time summary of what’s 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. Collate includes an asset if it matches any rule.

Step 6: Create & Deploy

​

Configure Metadata Agent and Schedule Ingestion

1. In the left navigation, click Connections and select your service.
2. Click the Agents tab.
3. 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.
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.

     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.
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.
