Note:

  1. You must run ingestion for both dbt and your data warehouse (target platform). They can be run in any order.
  2. It generates column lineage between the dbt nodes (e.g. when a model/snapshot depends on a dbt source or ephemeral model) as well as lineage between the dbt nodes and the underlying target platform nodes (e.g. BigQuery Table -> dbt source, dbt model -> BigQuery table/view).
  3. It automatically generates "sibling" relationships between the dbt nodes and the target / data warehouse nodes. These nodes will show up in the UI with both platform logos.
  4. We also support automated actions (like add a tag, term or owner) based on properties defined in dbt meta.

Setup​

The artifacts used by this source are:

  • dbt manifest file
    • This file contains model, source, tests and lineage data.
  • dbt catalog file
    • This file contains schema data.
    • dbt does not record schema data for Ephemeral models, as such datahub will show Ephemeral models in the lineage, however there will be no associated schema for Ephemeral models
  • dbt sources file
    • This file contains metadata for sources with freshness checks.
    • We transfer dbt's freshness checks to DataHub's last-modified fields.
    • Note that this file is optional – if not specified, we'll use time of ingestion instead as a proxy for time last-modified.
  • dbt run_results file
    • This file contains metadata from the result of a dbt run, e.g. dbt test
    • When provided, we transfer dbt test run results into assertion run events to see a timeline of test runs on the dataset

To generate these files, we recommend this workflow for dbt build and datahub ingestion.

dbt source snapshot-freshness
dbt build
cp target/run_results.json target/run_results_backup.json
dbt docs generate
cp target/run_results_backup.json target/run_results.json

# Run datahub ingestion, pointing at the files in the target/ directory

The necessary artifact files will then appear in the target/ directory of your dbt project.

We also have guides on handling more complex dbt orchestration techniques and multi-project setups below.

Entity is in manifest but missing from catalog

This warning usually appears when the catalog.json file was not generated by a dbt docs generate command. Most other dbt commands generate a partial catalog file, which may impact the completeness of the metadata in ingested into DataHub.

Following the above workflow should ensure that the catalog file is generated correctly.

boolean
When enabled, converts column URNs to lowercase to ensure cross-platform compatibility. If target_platform is Snowflake, the default is True.
Default: False
enable_meta_mapping
boolean
When enabled, applies the mappings that are defined through the meta_mapping directives.
Default: True
enable_owner_extraction
boolean
When enabled, ownership info will be extracted from the dbt meta

boolean
When enabled, applies the mappings that are defined through the query_tag_mapping directives.
Default: True
include_column_lineage
boolean
When enabled, column-level lineage will be extracted from the dbt node definition. Requires infer_dbt_schemas to be enabled. If you run into issues where the column name casing does not match up with properly, providing a datahub_api or using the rest sink will improve accuracy.
Default: True
include_compiled_code
boolean
When enabled, includes the compiled code in the emitted metadata.
Default: True
include_env_in_assertion_guid
boolean
Prior to version 0.9.4.2, the assertion GUIDs did not include the environment. If you're using multiple dbt ingestion that are only distinguished by env, then you should set this flag to True.
Default: False
incremental_lineage
boolean
When enabled, emits incremental/patch lineage for non-dbt entities. When disabled, re-states lineage on each run.
Default: True
infer_dbt_schemas

mapping rules that will be executed against dbt meta properties. Refer to the section below on dbt meta automated mappings.
Default: {}
only_include_if_in_catalog
boolean
[experimental] If true, only include nodes that are also present in the catalog file. This is useful if you only want to include models that have been built by the associated run.

dbt meta automated mappings​

dbt allows authors to define meta properties for datasets. Checkout this link to know more - dbt meta. Our dbt source allows users to define actions such as add a tag, term or owner. For example if a dbt model has a meta config "has_pii": True, we can define an action that evaluates if the property is set to true and add, lets say, a pii tag. To leverage this feature we require users to define mappings as part of the recipe. The following section describes how you can build these mappings. Listed below is a meta_mapping and column_meta_mapping section that among other things, looks for keys like business_owner and adds owners that are listed there.

meta_mapping:
  business_owner:
    match: ".*"
    operation: "add_owner"
    config:
      owner_type: user
      owner_category: BUSINESS_OWNER
  has_pii:
    match: True
    operation: "add_tag"
    config:
      tag: "has_pii_test"
  int_property:
    match: 1
    operation: "add_tag"
    config:
      tag: "int_meta_property"
  double_property:
    match: 2.5
    operation: "add_term"
    config:
      term: "double_meta_property"
  data_governance.team_owner:
    match: "Finance"
    operation: "add_term"
    config:
      term: "Finance_test"
  terms_list:
    match: ".*"
    operation: "add_terms"
    config:
      separator: ","
  documentation_link:
    match: "(?:https?)?\:\/\/\w*[^#]*"
    operation: "add_doc_link"
    config:
      link: {{ $match }}
      description: "Documentation Link"
column_meta_mapping:
  terms_list:
    match: ".*"
    operation: "add_terms"
    config:
      separator: ","
  is_sensitive:
    match: True
    operation: "add_tag"
    config:
      tag: "sensitive"

We support the following operations:

  1. add_tag - Requires tag property in config.

  2. add_term - Requires term property in config.

  3. add_terms - Accepts an optional separator property in config.

  4. add_owner - Requires owner_type property in config which can be either user or group. Optionally accepts the owner_category config property which can be set to either a custom ownership type urn like urn:li:ownershipType:architect or one of ['TECHNICAL_OWNER', 'BUSINESS_OWNER', 'DATA_STEWARD', 'DATAOWNER' (defaults to DATAOWNER).

    • The owner_type property will be ignored if the owner is a fully qualified urn.
    • You can use commas to specify multiple owners - e.g. business_owner: "jane,john,urn:li:corpGroup:data-team".

  5. add_doc_link - Requires link and description properties in config. Upon ingestion run, this will overwrite current links in the institutional knowledge section with this new link. The anchor text is defined here in the meta_mappings as description.

Note:

  1. The dbt meta_mapping config works at the model level, while the column_meta_mapping config works at the column level. The add_owner operation is not supported at the column level.
  2. For string meta properties we support regex matching.

With regex matching, you can also use the matched value to customize how you populate the tag, term or owner fields. Here are a few advanced examples:

Data Tier - Bronze, Silver, Gold​

If your meta section looks like this:

meta:
  data_tier: Bronze # chosen from [Bronze,Gold,Silver]

and you wanted to attach a glossary term like urn:li:glossaryTerm:Bronze for all the models that have this value in the meta section attached to them, the following meta_mapping section would achieve that outcome:

meta_mapping:
  data_tier:
    match: "Bronze|Silver|Gold"
    operation: "add_term"
    config:
      term: "{{ $match }}"

to match any data_tier of Bronze, Silver or Gold and maps it to a glossary term with the same name.

Case Numbers - create tags​

If your meta section looks like this:

meta:
  case: PLT-4678 # internal Case Number

and you want to generate tags that look like case_4678 from this, you can use the following meta_mapping section:

meta_mapping:
  case:
    match: "PLT-(.*)"
    operation: "add_tag"
     config:
       tag: "case_{{ $match }}"

Stripping out leading @ sign​

You can also match specific groups within the value to extract subsets of the matched value. e.g. if you have a meta section that looks like this:

meta:
  owner: "@finance-team"
  business_owner: "@janet"

and you want to mark the finance-team as a group that owns the dataset (skipping the leading @ sign), while marking janet as an individual user (again, skipping the leading @ sign) that owns the dataset, you can use the following meta-mapping section.

meta_mapping:
  owner:
    match: "^@(.*)"
    operation: "add_owner"
    config:
      owner_type: group
  business_owner:
    match: "^@(?P<owner>(.*))"
    operation: "add_owner"
    config:
      owner_type: user
      owner_category: BUSINESS_OWNER

In the examples above, we show two ways of writing the matching regexes. In the first one, ^@(.*) the first matching group (a.k.a. match.group(1)) is automatically inferred. In the second example, ^@(?P<owner>(.*)), we use a named matching group (called owner, since we are matching an owner) to capture the string we want to provide to the ownership urn.

dbt query_tag automated mappings​

This works similarly as the dbt meta mapping but for the query tags

We support the below actions -

  1. add_tag - Requires tag property in config.

The below example set as global tag the query tag tag key's value.

"query_tag_mapping":
{
   "tag":
      "match": ".*"
      "operation": "add_tag"
      "config":
        "tag": "{{ $match }}"
}

Integrating with dbt test​

To integrate with dbt tests, the dbt source needs access to the run_results.json file generated after a dbt test or dbt build execution. Typically, this is written to the target directory. A common pattern you can follow is:

  1. Run dbt build
  2. Copy the target/run_results.json file to a separate location. This is important, because otherwise subsequent dbt commands will overwrite the run results.
  3. Run dbt docs generate to generate the manifest.json and catalog.json files
  4. The dbt source makes use of the manifest, catalog, and run results file, and hence will need to be moved to a location accessible to the dbt source (e.g. s3 or local file system). In the ingestion recipe, the run_results_paths config must be set to the location of the run_results.json file from the dbt build or dbt test run.

The connector will produce the following things:

  • Assertion definitions that are attached to the dataset (or datasets)
  • Results from running the tests attached to the timeline of the dataset
Missing test results?

The most common reason for missing test results is that the run_results.json with the test result information is getting overwritten by a subsequent dbt command. We recommend copying the run_results.json file before running other dbt commands.

Separating test result emission from other metadata emission​

You can segregate emission of test results from the emission of other dbt metadata using the entities_enabled config flag. The following recipe shows you how to emit only test results.

source:
  type: dbt
  config:
    manifest_path: _path_to_manifest_json
    catalog_path: _path_to_catalog_json
    run_results_paths:
      - _path_to_run_results_json
    target_platform: postgres
    entities_enabled:
      test_results: Only

Similarly, the following recipe shows you how to emit everything (i.e. models, sources, seeds, test definitions) but not test results:

source:
  type: dbt
  config:
    manifest_path: _path_to_manifest_json
    catalog_path: _path_to_catalog_json
    run_results_paths:
      - _path_to_run_results_json
    target_platform: postgres
    entities_enabled:
      test_results: No

Multiple dbt projects​

In more complex dbt setups, you may have multiple dbt projects, where models from one project are used as sources in another project. DataHub supports this setup natively.

Each dbt project should have its own dbt ingestion recipe, and the platform_instance field in the recipe should be set to the dbt project name.

For example, if you have two dbt projects analytics and data_mart, you would have two ingestion recipes. If you have models in the data_mart project that are used as sources in the analytics project, the lineage will be automatically captured.

# Analytics dbt project
source:
  type: dbt
  config:
    platform_instance: analytics
    target_platform: postgres
    manifest_path: analytics/target/manifest.json
    catalog_path: analytics/target/catalog.json
    # ... other configs
# Data Mart dbt project
source:
  type: dbt
  config:
    platform_instance: data_mart
    target_platform: postgres
    manifest_path: data_mart/target/manifest.json
    catalog_path: data_mart/target/catalog.json
    # ... other configs

If you have models that have tons of sources from other projects listed in the "Composed Of" section, it may also make sense to hide sources.

Reducing "composed of" sprawl by hiding sources​

When many dbt projects use a single table as a source, the "Composed Of" relationships can become very large and difficult to navigate and extra source nodes can clutter the lineage graph.

This is particularly useful for multi-project setups, but can be useful in single-project setups as well.

The benefit is that your entire dbt estate becomes much easier to navigate, and the borders between projects less noticeable. The downside is that we will not pick up any documentation or meta mappings applied to dbt sources.

To enable this, set entities_enabled.sources: No and skip_sources_in_lineage: true in your dbt source config:

source:
  type: dbt
  config:
    platform_instance: analytics
    target_platform: postgres
    manifest_path: analytics/target/manifest.json
    catalog_path: analytics/target/catalog.json
    # ... other configs
    entities_enabled:
      sources: No
    skip_sources_in_lineage: true

[Experimental] It's also possible to use skip_sources_in_lineage: true without disabling sources entirely. If you do this, sources will not participate in the lineage graph - they'll have upstreams but no downstreams. However, they will still contribute to docs, tags, etc to the warehouse entity.

Setup​

This source pulls dbt metadata directly from the dbt Cloud APIs.

Create a service account token with the "Metadata Only" permission. This is a read-only permission.

You'll need to have a dbt Cloud job set up to run your dbt project, and "Generate docs on run" should be enabled.

To get the required IDs, go to the job details page (this is the one with the "Run History" table), and look at the URL. It should look something like this: https://cloud.getdbt.com/next/deploy/107298/projects/175705/jobs/148094. In this example, the account ID is 107298, the project ID is 175705, and the job ID is 148094.

When enabled, column-level lineage will be extracted from the dbt node definition. Requires infer_dbt_schemas to be enabled. If you run into issues where the column name casing does not match up with properly, providing a datahub_api or using the rest sink will improve accuracy.
Default: True
include_compiled_code
boolean
When enabled, includes the compiled code in the emitted metadata.
Default: True
include_env_in_assertion_guid
boolean
Prior to version 0.9.4.2, the assertion GUIDs did not include the environment. If you're using multiple dbt ingestion that are only distinguished by env, then you should set this flag to True.
Default: False
incremental_lineage
boolean
When enabled, emits incremental/patch lineage for non-dbt entities. When disabled, re-states lineage on each run.
Default: True
infer_dbt_schemas
boolean
When enabled, schemas will be inferred from the dbt node definition.
Default: True
meta_mapping
object
mapping rules that will be executed against dbt meta properties. Refer to the section below on dbt meta automated mappings.
Default: {}
metadata_endpoint
string
The dbt Cloud metadata API endpoint. If not provided, we will try to infer it from the access_url.
Default: https://metadata.cloud.getdbt.com/graphql
owner_extraction_pattern
string
Regex string to extract owner from the dbt node using the (?P<name>...) syntax of the match object, where the group name must be owner. Examples: (1)r"(?P<owner>(.*)): (\w+) (\w+)" will extract jdoe as the owner from "jdoe: John Doe" (2) r"@(?P<owner>(.*))" will extract alice as the owner from "@alice".
platform_instance
string
The instance of the platform that all assets produced by this recipe belong to. This should be unique within the platform. See https://datahubproject.io/docs/platform-instances/ for more details.
prefer_sql_parser_lineage
boolean
Normally we use dbt's metadata to generate table lineage. When enabled, we prefer results from the SQL parser when generating lineage instead. This can be useful when dbt models reference tables directly, instead of using the ref() macro. This requires that skip_sources_in_lineage is enabled.
Default: False
query_tag_mapping
object
mapping rules that will be executed against dbt query_tag meta properties. Refer to the section below on dbt meta automated mappings.
Default: {}
run_id
integer
The ID of the run to ingest metadata from. If not specified, we'll default to the latest run.
skip_sources_in_lineage
boolean
[Experimental] When enabled, dbt sources will not be included in the lineage graph. Requires that entities_enabled.sources is set to NO. This is mainly useful when you have multiple, interdependent dbt projects.
Default: False
strip_user_ids_from_email
boolean
Whether or not to strip email id while adding owners using dbt meta actions.
Default: False
tag_prefix
string
Prefix added to tags during ingestion.
Default: dbt:
target_platform_instance
string
The platform instance for the platform that dbt is operating on. Use this if you have multiple instances of the same platform (e.g. redshift) and need to distinguish between them.
test_warnings_are_errors
boolean
When enabled, dbt test warnings will be treated as failures.
Default: False
use_identifiers
boolean
Use model identifier instead of model name if defined (if not, default to model name).
Default: False
write_semantics
string
Whether the new tags, terms and owners to be added will override the existing ones added only by this source or not. Value for this config can be "PATCH" or "OVERRIDE"
Default: PATCH
env
string
Environment to use in namespace when constructing URNs.
Default: PROD
entities_enabled
DBTEntitiesEnabled
Controls for enabling / disabling metadata emission for different dbt entities (models, test definitions, test results, etc.)
Default: {'models': 'YES', 'sources': 'YES', 'seeds': 'YES'...
entities_enabled.model_performance
Enum
Emit model performance metadata when set to Yes or Only. Only supported with dbt core.
Default: YES
entities_enabled.models
Enum
Emit metadata for dbt models when set to Yes or Only
Default: YES
entities_enabled.seeds
Enum
Emit metadata for dbt seeds when set to Yes or Only
Default: YES
entities_enabled.snapshots
Enum
Emit metadata for dbt snapshots when set to Yes or Only
Default: YES
entities_enabled.sources
Enum
Emit metadata for dbt sources when set to Yes or Only
Default: YES
entities_enabled.test_definitions
Enum
Emit metadata for test definitions when enabled when set to Yes or Only
Default: YES
entities_enabled.test_results
Enum
Emit metadata for test results when set to Yes or Only
Default: YES
node_name_pattern
AllowDenyPattern
regex patterns for dbt model names to filter in ingestion.
Default: {'allow': ['.*'], 'deny': [], 'ignoreCase': True}
node_name_pattern.ignoreCase
boolean
Whether to ignore case sensitivity during pattern matching.
Default: True
node_name_pattern.allow
array
List of regex patterns to include in ingestion
Default: ['.*']
node_name_pattern.allow.string
string
node_name_pattern.deny
array
List of regex patterns to exclude from ingestion.
Default: []
node_name_pattern.deny.string
string
stateful_ingestion
StatefulStaleMetadataRemovalConfig
DBT Stateful Ingestion Config.
stateful_ingestion.enabled
boolean
Whether or not to enable stateful ingest. Default: True if a pipeline_name is set and either a datahub-rest sink or datahub_api is specified, otherwise False
Default: False
stateful_ingestion.remove_stale_metadata
boolean
Soft-deletes the entities present in the last successful run but missing in the current run with stateful_ingestion enabled.
Default: True
