no-code framework that allows you to configure broad-spanning monitors & continuous actions
|
||
for the data assets - datasets, dashboards, charts, pipelines - that make up your enterprise Metadata Graph.
|
||
At the center of this framework is the concept of a Metadata Test.</p><p>There are two powerful use cases that are uniquely enabled by the Metadata Tests framework:</p><ol><li>Automated Asset Classification</li><li>Automated Metadata Completion Monitoring</li></ol><h3 class="anchor anchorWithStickyNavbar_LWe7" id="automated-asset-classification">Automated Asset Classification<a href="#automated-asset-classification" class="hash-link" aria-label="Direct link to Automated Asset Classification" title="Direct link to Automated Asset Classification"></a></h3><p>Metadata Tests allows you to define conditions for selecting a subset of data assets (e.g. datasets, dashboards, etc),
|
||
along with a set of actions to take for entities that are selected. After the test is defined, the actions
|
||
will be applied continuously over time, as the selection set evolves & changes with your data ecosystem.</p><p>When defining selection criteria, you'll be able to choose from a range of useful technical signals (e.g. usage, size) that are automatically
|
||
extracted by DataHub (which vary by integration). This makes automatically classifying the "important" assets in your organization quite easy, which
|
||
is in turn critical for running effective Data Governance initiatives within your organization.</p><p>For example, we can define a Metadata Test which selects all Snowflake Tables which are in the top 10% of "most queried"
|
||
for the past 30 days, and then assign those Tables to a special "Tier 1" group using DataHub Tags, Glossary Terms, or Domains.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="automated-data-governance-monitoring">Automated Data Governance Monitoring<a href="#automated-data-governance-monitoring" class="hash-link" aria-label="Direct link to Automated Data Governance Monitoring" title="Direct link to Automated Data Governance Monitoring"></a></h3><p>Metadata Tests allow you to define & monitor a set of rules that apply to assets in your data ecosystem (e.g. datasets, dashboards, etc). This is particularly useful when attempting to govern
|
||
your data, as it allows for the (1) definition and (2) measurement of centralized metadata standards, which are key for both bootstrapping
|
||
and maintaining a well-governed data ecosystem.</p><p>For example, we can define a Metadata Test which requires that all "Tier 1" data assets (e.g. those marked with a special Tag or Glossary Term),
|
||
must have the following metadata:</p><ol><li>At least 1 explicit owner <em>and</em></li><li>High-level, human-authored documentation <em>and</em></li><li>At least 1 Glossary Term from the "Classification" Term Group</li></ol><p>Then, we can closely monitor which assets are passing and failing these rules as we work to improve things over time.
|
||
We can easily identify assets that are <em>in</em> and <em>out of</em> compliance with a set of centrally-defined standards.</p><p>By applying automation, Metadata Tests
|
||
can enable the full lifecycle of complex Data Governance initiatives - from scoping to execution to monitoring.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="metadata-tests-setup-prerequisites-and-permissions">Metadata Tests Setup, Prerequisites, and Permissions<a href="#metadata-tests-setup-prerequisites-and-permissions" class="hash-link" aria-label="Direct link to Metadata Tests Setup, Prerequisites, and Permissions" title="Direct link to Metadata Tests Setup, Prerequisites, and Permissions"></a></h2><p>What you need to manage Metadata Tests on DataHub:</p><ul><li><strong>Manage Tests</strong> Privilege</li></ul><p>This Platform Privilege allows users to create, edit, and remove all Metadata Tests on DataHub. Therefore, it should only be

Defining Selection Criteria (Scope)" title="Direct link to Step 1. Defining Selection Criteria (Scope)"></a></h4><p>In the first step, we define a set of conditions that are used to select a subset of the assets in our Metadata Graph
|
||
that will be "in the scope" of the new test. Assets that <strong>match</strong> the selection conditions will be considered in scope, while those which do not are simply not applicable for the test.

Once the test is created, the test will be evaluated for any assets which fall in scope on a continuous basis (when an asset changes on DataHub

or once every day).</p><h5 class="anchor anchorWithStickyNavbar_LWe7" id="selecting-asset-types">Selecting Asset Types<a href="#selecting-asset-types" class="hash-link" aria-label="Direct link to Selecting Asset Types" title="Direct link to Selecting Asset Types"></a></h5><p>You must select at least one asset <em>type</em> from a set that includes Datasets, Dashboards, Charts, Data Flows (Pipelines), Data Jobs (Tasks),

Each <strong>Property</strong> condition consists of a target <em>property</em>,
|
||
an <em>operator</em>, and an optional <em>value</em>.</p><p>A <em>property</em> is an attribute of a data asset. It can either be a technical signal (e.g. <strong>metric</strong> such as usage, storage size) or a<br>
|
||
<!-- -->metadata signal (e.g. owners, domain, glossary terms, tags, and more), depending on the asset type and applicability of the signal.
|
||
The full set of supported <em>properties</em> can be found in the table below.</p><p>An <em>operator</em> is the type of predicate that will be applied to the selected <em>property</em> when evaluating the test for an asset. The types
|
||
of operators that are applicable depend on the selected property. Some examples of operators include <code>Equals</code>, <code>Exists</code>, <code>Matches Regex</code>,
|
||
and <code>Contains</code>.</p><p>A <em>value</em> defines the right-hand side of the condition, or a pre-configured value to evaluate the property and operator against. The type of the value
|
||
is dependent on the selected <em>property</em> and <em>operator. For example, if the selected </em>operator<!-- -->*<!-- --> is <code>Matches Regex</code>, the type of the
|
||
value would be a string.</p><p>By selecting a property, operator, and value, we can create a single condition (or predicate) used for
|
||
selecting a data asset to be tested. For example, we can build property conditions that match:</p><ul><li>All datasets in the top 25% of query usage in the past 30 days</li><li>All assets that have the "Tier 1" Glossary Term attached</li><li>All assets in the "Marketing" Domain</li><li>All assets without owners</li><li>All assets without a description</li></ul><p>To create a <strong>Property</strong> condition, simply click <strong>Add Condition</strong> then select <strong>Property</strong> condition.</p><p align="center"><img loading="lazy" width="80%" src="https://raw.githubusercontent.com/datahub-project/static-assets/main/imgs/metadata-test-create-property-condition.png" class="img_ev3q"></p><p>We can combine <strong>Property</strong> conditions using boolean operators including <code>AND</code>, <code>OR</code>, and <code>NOT</code>, by
|
||
creating <strong>Logical</strong> conditions. To create a <strong>Logical</strong> condition, simply click <strong>Add Condition</strong> then select an
|
||
<strong>And</strong>, <strong>Or</strong>, or <strong>Not</strong> condition.</p><p align="center"><img loading="lazy" width="80%" src="https://raw.githubusercontent.com/datahub-project/static-assets/main/imgs/metadata-test-create-logical-condition.png" class="img_ev3q"></p><p>Logical conditions allow us to accommodate complex real-world selection requirements:</p><ul><li>All Snowflake Tables that are in the Top 25% of most queried AND do not have a Domain</li><li>All Looker Dashboards that do not have a description authored in Looker OR in DataHub</li></ul><h4 class="anchor anchorWithStickyNavbar_LWe7" id="step-2-defining-rules">Step 2: Defining Rules<a href="#step-2-defining-rules" class="hash-link" aria-label="Direct link to Step 2: Defining Rules" title="Direct link to Step 2: Defining Rules"></a></h4><p>In the second step, we can define a set of conditions that selected assets must match in order to be "passing" the test.
|
||
To do so, we can construct another set of <strong>Property</strong> conditions (as described above).</p><blockquote><p><strong>Pro-Tip</strong>: If no rules are supplied, then all assets that are selected by the criteria defined in Step 1 will be considered "passing".
|
||
If you need to apply an automated Action to the selected assets, you can leave the Rules blank and continue to the next step.</p></blockquote><p align="center"><img loading="lazy" width="50%" src="https://raw.githubusercontent.com/datahub-project/static-assets/main/imgs/metadata-test-create-rules.png" class="img_ev3q"></p><p>When combined with the selection criteria, Rules allow us to define complex, highly custom <strong>Data Governance</strong> policies such as:</p><ul><li>All datasets in the top 25% of query usage in the past 30 days <strong>must have an owner</strong>.</li><li>All assets in the "Marketing" Domain <strong>must have a description</strong></li><li>All Snowflake Tables that are in the Top 25% of most queried AND do not have a Domain <strong>must have

|

match our expectations by testing them against some existing assets indexed by DataHub.</p><p>To verify your Test conditions, simply click <strong>Try it out</strong>, find an asset to test against by searching & filtering down your assets,

and finally click <strong>Run Test</strong> to see whether the asset is passes or fails the provided conditions.</p><p align="center"><img loading="lazy" width="80%" src="https://raw.githubusercontent.com/datahub-project/static-assets/main/imgs/metadata-test-validate-conditions.png" class="img_ev3q"></p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="step-3-defining-actions-optional">Step 3: Defining Actions (Optional)<a href="#step-3-defining-actions-optional" class="hash-link" aria-label="Direct link to Step 3: Defining Actions (Optional)" title="Direct link to Step 3: Defining Actions (Optional)"></a></h4><blockquote><p>If you don't wish to take any actions for assets that pass or fail the test, simply click 'Skip'.</p></blockquote><p>In the third step, we can define a set of Actions that will be automatically applied to each selected asset which passes or fails the Rules conditions.</p><p>For example, we may wish to mark <strong>passing</strong> assets with a special DataHub Tag or Glossary Term (e.g. "Tier 1"), or remove these special marking for those which are failing.
|

This allows us to automatically control classifications of data assets as they move in and out of compliance with the Rules defined in Step 2.</p><p>A few of the supported Action types include:</p><ul><li>Adding or removing specific Tags</li><li>Adding or removing specific Glossary Terms</li><li>Adding or removing specific Owners</li><li>Adding or removing to a specific Domain</li></ul><p align="center"><img loading="lazy" width="80%" src="https://raw.githubusercontent.com/datahub-project/static-assets/main/imgs/metadata-test-define-actions.png" class="img_ev3q"></p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="step-4-name-category-description">Step 4: Name, Category, Description<a href="#step-4-name-category-description" class="hash-link" aria-label="Direct link to Step 4: Name, Category, Description" title="Direct link to Step 4: Name, Category, Description"></a></h4><p>In the final step, we can add a freeform name, category, and description for our new Metadata Test.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="viewing-test-results">Viewing Test Results<a href="#viewing-test-results" class="hash-link" aria-label="Direct link to Viewing Test Results" title="Direct link to Viewing Test Results"></a></h3><p>Metadata Test results can be viewed in 2 places:</p><ol><li>On an asset profile page (e.g. Dataset profile page), inside the <strong>Validation</strong> tab.</li><li>On the Metadata Tests management page.

This feature is typically disabled by default. It can be enabled on demand, subject to disussion.</p></li><li><p><strong>Scheduled evaluation</strong>: A dedicated Metadata Test evaluator runs on a recurring schedule (typically every 24 hours) and evaluates all tests against the entire Metadata Graph. The cadence can be adjusted. It can be made more frequent in limited cases where metadata is small, subject to discussion.</p></li></ol><p>Both scenarios have increased server load concerns which may require additional server resources and consultation with your Acryl representative for the associated cost.</p><p><strong>Can I configure a custom evaluation schedule for my Metadata Test?</strong></p><p>No, you cannot. Currently, the internal evaluator will ensure that tests are run continuously for
|
||
each asset, regardless of whether it is being changed on DataHub.</p><p><strong>How is a Metadata Test different from an Assertion?</strong></p><p>An Assertion is a specific test, similar to a unit test, that is defined for a single data asset. Typically,
|
||
it will include domain-specific knowledge about the asset and test against physical attributes of it. For example, an Assertion
|
||
may verify that the number of rows for a specific table in Snowflake falls into a well-defined range.</p><p>A Metadata Test is a broad spanning predicate which applies to a subset of the Metadata Graph (e.g. across multiple
|
||
data assets). Typically, it is defined against <em>metadata</em> attributes, as opposed to the physical data itself. For example,
|
||
a Metadata Test may verify that ALL tables in Snowflake have at least 1 assigned owner, and a human-authored description.
|
||
Metadata Tests allow you to manage broad policies across your entire data ecosystem driven by metadata, for example to
|
||
augment a larger scale Data Governance initiative.</p></div><footer class="theme-doc-footer docusaurus-mt-lg"><div class="slackUtm_uoBr"><div class="slackUtm_uoBr"><hr>Need more help?
