K provides context and trust to your data items by helping you understand the lineage and relationships between data items.

You can see where your data item sources data from, where it flows to, how it joins to other data items.

Lineage crosses different item types, from tables to reports, across different sources. K automatically generates lineage across these item. Where it can’t, lineage can be manually added via the UI or via the API.

Column level lineage is coming in Q2 2022


Using Lineage

You can access Lineage by going to any profile page and clicking on the Lineage tab

Lineage views

There are several types of views for lineage

View

Description

Best for

Basic

This view shows high level lineage between tables, reports, pipelines. Items like code are hidden.

This is the default view for all item types except for code.

To check where a specific item sources its data from, and if those sources are trusted.

In Depth

This view shows detailed lineage between items including code that connects them.

This is the default view for code

To investigate how data items are connected and what logic might be used to filter data.

List

This view lists all the immediate up and downstream data items.

If more than 50 items are connected in lineage, it is best to use the list to see them all.

Navigating the Lineage chart

The lineage chart should be read Left to Right. Items to the left are upstream (they provide data to) of the assets on the right.

  1. Some items have lineage that can be displayed. They will appear with a + sign that you can click to expand

  2. You can click automated links to see the details to join the two items. This might be code or a pipeline that connects the two

  3. The current target you are looking at will be highlighted in Blue

The details panel

When you click on a data item or an automated link a panel will appear to provide additional details

In a Data Item details panel you will see

  1. Details about the data item including any tags, collections, and descriptions

  2. Properties about the data item include its type, trust score, classification etc

  3. Action buttons that are relevant to the data item

In a Link details panel you will see

  1. The data item (code, pipelines) that join the two data items

  2. Details of the data item like the actual code used

  3. Action buttons that are relevant to the data item


Accessing Lineage Explorer

The Lineage explorer is useful to see complex lineage that might require more screen real estate.

You can access the Impact Assessment through the Data Applications page or the Data Item’s Profile Page (e.g. table profile)

Access via Data Applications on the side bar

Access via your Data Item’s Profile Page and clicking on the Lineage Tab / Explorer or via the Open in applications button at the top

If you select the Lineage Explorer via the profile page, the data details will automatically pre-populate


Updating Lineage Data

Sometimes lineage may be missing on a table (or other item). To update the Lineage information, first go to the Data Item’s Profile Page

  1. Click Link and a pop-up box will appear

  2. Confirm if you want to add an Upstream or Downstream item

  3. Search for the missing data item and click Close
