Dremio

Important Capabilities

Capability	Status	Notes
Data Profiling	✅	Optionally enabled via configuration
Detect Deleted Entities	✅	Optionally enabled via stateful_ingestion.remove_stale_metadata
Domains	✅	Supported via the domain config field
Platform Instance	✅	Enabled by default
Table-Level Lineage	✅	Enabled by default

This plugin extracts the following:

• Metadata for databases, schemas, views and tables
• Column types associated with each table
• Table, row, and column statistics via optional SQL profiling
• Lineage information for views and datasets

CLI based Ingestion

Install the Plugin

The dremio source works out of the box with acryl-datahub.

Starter Recipe

Check out the following recipe to get started with ingestion! See below for full configuration options.

For general pointers on writing and running a recipe, see our main recipe guide.

source:
  type: dremio
  config:
    # Coordinates
    hostname: localhost
    port: 26257

    # Credentials
    authentication_method: password
    username: user
    password: pass

sink:
  # sink configs
