Druid

For context on getting started with ingestion, check out our metadata ingestion guide.

Setup#

To install this plugin, run pip install 'acryl-datahub[druid]'.

Capabilities#

This plugin extracts the following:

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

Note: It is important to explicitly define the deny schema pattern for internal Druid databases (lookup & sys) if adding a schema pattern. Otherwise, the crawler may crash before processing relevant databases. This deny pattern is defined by default but is overriden by user-submitted configurations.

Quickstart 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: druid  config:    # Coordinates    host_port: "localhost:8082"
    # Credentials    username: admin    password: password
sink:  # sink configs

Config details#

Note that a . is used to denote nested fields in the YAML recipe.

As a SQL-based service, the Athena integration is also supported by our SQL profiler. See here for more details on configuration.
