Dremio

BETA
In this section, we provide guides and references to use the Dremio connector. Configure and schedule Dremio metadata workflows from the Collate UI:

Requirements

Dremio connector supports both:
  • Dremio Cloud (SaaS): Fully managed cloud platform
  • Dremio Software: Self-hosted on-premises or in your own cloud infrastructure

Dremio Cloud Requirements

To connect to Dremio Cloud, you will need:
  • Cloud Region: The region where your Dremio Cloud organization is hosted (US or EU)
  • Personal Access Token (PAT): A token generated from your Dremio Cloud account settings
  • Project ID: Your Dremio Cloud project identifier

Generate a Personal Access Token

  1. Log into your Dremio Cloud account.
  2. Navigate to Settings > Personal Access Tokens.
  3. Select Add Token.
  4. Provide a description (for example, “Collate Integration”).
  5. Set an expiration period.
  6. Select Create.
  7. Copy the generated token.

Find your Project ID

  1. Log into your Dremio Cloud account.
  2. Check the URL in your browser: https://app.dremio.cloud/projects/{PROJECT_ID}/....
  3. The Project ID is the alphanumeric string after /projects/.
  4. Alternatively, go to Project Settings to view your Project ID.

Dremio Software Requirements

To connect to Dremio Software (self-hosted), you will need:
  • Host and Port: The URL of your Dremio Software instance (for example, http://localhost:9047 or https://dremio.example.com:9047)
  • Username: A user account with privileges to read catalog metadata
  • Password: The password for the user account

Permissions Required

Dremio Cloud

  • Catalog Access: Ability to view sources and spaces
  • Dataset Read: Permission to view datasets and their metadata
  • Query History (optional): Access to sys.project.history.jobs for usage and lineage extraction

Dremio Software

  • Catalog Access: Ability to view sources and spaces
  • Dataset Read: Permission to view datasets and their metadata
  • System Tables (optional): Access to job history tables in the sys schema for usage and lineage extraction
The connector uses Dremio’s REST API and SQL interfaces for metadata extraction. Access to query history is optional. If the user does not have permission to access job history, metadata extraction will still work, but usage and lineage information will not be available.

Metadata Ingestion

1

Visit the Services Page

Click `Settings` in the side navigation bar and then `Services`. The first step is to ingest the metadata from your sources. To do that, you first need to create a Service connection first. This Service will be the bridge between OpenMetadata and your source system. Once a Service is created, it can be used to configure your ingestion workflows.Visit Services Page
2

Create a New Service

Click on _Add New Service_ to start the Service creation.Create a new Service
3

Select the Service Type

Select Dremio as the Service type and click _Next_.Select Service
4

Name and Describe your Service

Provide a name and description for your Service.

Service Name

OpenMetadata uniquely identifies Services by their **Service Name**. Provide a name that distinguishes your deployment from other Services, including the other Dremio Services that you might be ingesting metadata from. Note that when the name is set, it cannot be changed.Add New Service
5

Configure the Service Connection

In this step, we will configure the connection settings required for Dremio. Please follow the instructions below to properly configure the Service to read from your sources. You will also find helper documentation on the right-hand side panel in the UI.Configure Service connection

Connection Details

Connection Details

When using a Hybrid Ingestion Runner, any sensitive credential fields such as passwords, API keys, or private keys must reference secrets using the following format:
password: secret:/my/database/password
This applies only to fields marked as secrets in the connection form (these typically mask input and show a visibility toggle icon). For a complete guide on managing secrets in hybrid setups, see the Hybrid Ingestion Runner Secret Management Guide.
  • Authentication Type: Choose Dremio Cloud (SaaS) or Dremio Software (self-hosted).
  • region: Dremio Cloud region where your organization is hosted (US or EU).
  • personalAccessToken: Personal Access Token for authenticating with Dremio Cloud.
  • projectId: Dremio Cloud Project ID.
  • hostPort: URL to your self-hosted Dremio Software instance, including protocol and port.
  • username: Username for authenticating with Dremio Software.
  • password: Password for the Dremio Software user account.
  • database: Optional. Restrict metadata ingestion to a specific namespace (source or space).
  • databaseFilterPattern: Regex pattern to include or exclude namespaces (sources/spaces) based on their names.
  • schemaFilterPattern: Regex pattern to include or exclude folders based on their names.
  • tableFilterPattern: Regex pattern to include or exclude tables and views based on their names.

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. Advanced Configuration

Configure Metadata Ingestion

In this step we will configure the metadata ingestion pipeline, Please follow the instructions belowConfigure Metadata IngestionConfigure Metadata Ingestion

Metadata Ingestion Options

If the owner’s name is openmetadata, you need to enter [email protected] in the name section of add team/user form, click here for more info.
  • Name: This field refers to the name of ingestion pipeline, you can customize the name or use the generated name.
  • Database Filter Pattern (Optional): Use to database filter patterns to control whether or not to include database as part of metadata ingestion.
    • Include: Explicitly include databases by adding a list of comma-separated regular expressions to the Include field. OpenMetadata will include all databases with names matching one or more of the supplied regular expressions. All other databases will be excluded.
    • Exclude: Explicitly exclude databases by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all databases with names matching one or more of the supplied regular expressions. All other databases will be included.
  • Schema Filter Pattern (Optional): Use to schema filter patterns to control whether to include schemas as part of metadata ingestion.

    • Exclude: Explicitly exclude schemas by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all schemas with names matching one or more of the supplied regular expressions. All other schemas will be included.
  • Table Filter Pattern (Optional): Use to table filter patterns to control whether to include tables as part of metadata ingestion.
    • Include: Explicitly include tables by adding a list of comma-separated regular expressions to the Include field. OpenMetadata will include all tables with names matching one or more of the supplied regular expressions. All other tables will be excluded.
    • Exclude: Explicitly exclude tables by adding a list of comma-separated regular expressions to the Exclude field. OpenMetadata will exclude all tables with names matching one or more of the supplied regular expressions. All other tables will be included.
  • Enable Debug Log (toggle): Set the Enable Debug Log toggle to set the default log level to debug.
  • Mark Deleted Tables (toggle): Set the Mark Deleted Tables toggle to flag tables as soft-deleted if they are not present anymore in the source system.
  • Mark Deleted Tables from Filter Only (toggle): Set the Mark Deleted Tables from Filter Only toggle to flag tables as soft-deleted if they are not present anymore within the filtered schema or database only. This flag is useful when you have more than one ingestion pipelines. For example if you have a schema
  • includeTables (toggle): Optional configuration to turn off fetching metadata for tables.
  • includeViews (toggle): Set the Include views toggle to control whether to include views as part of metadata ingestion.
  • includeTags (toggle): Set the ‘Include Tags’ toggle to control whether to include tags as part of metadata ingestion.
  • includeOwners (toggle): Set the ‘Include Owners’ toggle to control whether to include owners to the ingested entity if the owner email matches with a user stored in the OM server as part of metadata ingestion. If the ingested entity already exists and has an owner, the owner will not be overwritten.

  • includeDDL (toggle): Optional configuration to toggle the DDL Statements ingestion.
  • queryLogDuration (Optional): Configuration to tune how far we want to look back in query logs to process Stored Procedures results.
  • queryParsingTimeoutLimit (Optional): Configuration to set the timeout for parsing the query in seconds.
  • useFqnForFiltering (toggle): Regex will be applied on fully qualified name (e.g service_name.db_name.schema_name.table_name) instead of raw name (e.g. table_name).
  • Incremental (Beta): Use Incremental Metadata Extraction after the first execution. This is done by getting the changed tables instead of all of them. Only Available for BigQuery, Redshift and Snowflake
    • Enabled: If True, enables Metadata Extraction to be Incremental.
    • lookback Days: Number of days to search back for a successful pipeline run. The timestamp of the last found successful pipeline run will be used as a base to search for updated entities.
    • Safety Margin Days: Number of days to add to the last successful pipeline run timestamp to search for updated entities.
  • Threads (Beta): Use a Multithread approach for Metadata Extraction. You can define here the number of threads you would like to run concurrently.
Note that the right-hand side panel in the OpenMetadata UI will also share useful documentation when configuring the ingestion.
