Browse Paths Upgrade (August 2022)


Up to this point, there's been a historical constraint on all entity browse paths. Namely, each browse path has been required to end with a path component that represents "simple name" for an entity. For example, a Browse Path for a Snowflake Table called "test_table" may look something like this:


In the UI, we artificially truncate the final path component when you are browsing the Entity hierarchy, so your browse experience would be:

prod > snowflake > warehouse1> db1 > Click Entity

As you can see, the final path component test_table is effectively ignored. It could have any value, and we would still ignore it in the UI. This behavior serves as a workaround to the historical requirement that all browse paths end with a simple name.

This data constraint stands in opposition the original intention of Browse Paths: to provide a simple mechanism for organizing assets into a hierarchical folder structure. For this reason, we've changed the semantics of Browse Paths to better align with the original intention. Going forward, you will not be required to provide a final component detailing the "name". Instead, you will be able to provide a simpler path that omits this final component:


and the browse experience from the UI will continue to work as you would expect:

prod > snowflake > warehouse1> db1 > Click Entity.

With this change comes a fix to a longstanding bug where multiple browse paths could not be attached to a single URN. Going forward, we will support producing multiple browse paths for the same entity, and allow you to traverse via multiple paths. For example

browse_path = BrowsePathsClass(
paths=["/powerbi/my/custom/path", "/my/other/custom/path"]
return MetadataChangeProposalWrapper(

Using the Python Emitter SDK to produce multiple Browse Paths for the same entity

We've received multiple bug reports, such as this issue, and requests to address these issues with Browse, and thus are deciding to do it now before more workarounds are created.

What this means for you

Once you upgrade to DataHub v0.8.45 you will immediately notice that traversing your Browse Path hierarchy will require one extra click to find the entity. This is because we are correctly displaying the FULL browse path, including the simple name mentioned above.

There will be 2 ways to upgrade to the new browse path format. Depending on your ingestion sources, you may want to use one or both:

  1. Migrate default browse paths to the new format by restarting DataHub
  2. Upgrade your version of the datahub CLI to push new browse path format (version v0.8.45)

Each step will be discussed in detail below.

1. Migrating default browse paths to the new format

To migrate those Browse Paths that are generated by DataHub by default (when no path is provided), simply restart the datahub-gms container / pod with a single additional environment variable:


And restart the datahub-gms instance. This will cause GMS to perform a boot-time migration of all your existing Browse Paths to the new format, removing the unnecessarily name component at the very end.

If the migration is successful, you'll see the following in your GMS logs:

18:58:17.414 [main] INFO c.l.m.b.s.UpgradeDefaultBrowsePathsStep:60 - Successfully upgraded all browse paths!

After this one-time migration is complete, you should be able to navigate the Browse hierarchy exactly as you did previously.

Note that certain ingestion sources actively produce their own Browse Paths, which overrides the default path computed by DataHub.

In these cases, getting the updated Browse Path will require re-running your ingestion process with the updated version of the connector. This is discussed in more detail in the next section.

2. Upgrading the datahub CLI to push new browse paths

If you are actively ingesting metadata from one or more of following sources

  1. Sagemaker
  2. Looker / LookML
  3. Feast
  4. Kafka
  5. Mode
  6. PowerBi
  7. Pulsar
  8. Tableau
  9. Business Glossary

You will need to upgrade the DataHub CLI to >= v0.8.45 and re-run metadata ingestion. This will generate the new browse path format and overwrite the existing paths for entities that were extracted from these sources.

If you are producing custom Browse Paths

If you've decided to produce your own custom Browse Paths to organize your assets (e.g. via the Python Emitter SDK), you'll want to change the code to produce those paths to truncate the final path component. For example, if you were previously emitting a browse path like this:


You can simply remove the final "suffix" piece:


Your users will be able to find the entity by traversing through these folders in the UI:

my > custom > browse> path > Click Entity.

Note that if you are using the Browse Path Transformer you will be impacted in the same way. It is recommended that you revisit the paths that you are producing, and update them to the new format.
