Find and apply suggestions to an asset

As a data team ourselves, we understand that metadata curation can be time-consuming. To streamline this process, each time you fill in a metadata gap, Atlan looks for opportunities to reuse that information.

This is where trident suggestions 🔱 come into play. It provides metadata suggestions for similar assets.

For example: CUSTOMER (table)

You add the description "Information about customers" to a table called CUSTOMER.

  • Atlan searches for other tables named CUSTOMER that lack a description.

  • Atlan then suggests "Information about customers" as the description for these other CUSTOMER tables.

In Atlan's SDK, you can use the Suggestions object to find and apply these recommendations to your assets.

Table table = Table.get(
    "default/snowflake/1720661835/db/schema/table"
); // (1)

SuggestionResponse response = Suggestions.finder(table) // (2)
    .include(Suggestions.TYPE.GroupOwners)
    .include(Suggestions.TYPE.UserDescription)
    .maxSuggestions(5)
    .withOtherType(View.TYPE_NAME)
    .includeArchived(false)
    .get(); // (3)

assertNotNull(response); // (4)
assertNotNull(response.getOwnerGroups());
assertNotNull(response.getUserDescriptions());
  1. First, you need to retrieve the asset for which you want to find suggestions.

  2. Start by building a Suggestions request by chaining the following methods:

    • finder: specify the asset for which you want to find suggestions.

    • include: add criteria to specify the types of suggestions to include in the search results. For this example, we're retrieving suggestions for GroupOwners and UserDescription.

      Want to find suggestions for ALL types?

      To include all suggestion types (description, owner, tags, and terms):

      Suggestions.includes(Arrays.asList(Suggestions.TYPE.values()))

    • maxSuggestions: (Optional) specify the maximum number of suggestions to return. Defaults to 5.

    • includeArchived: (Optional) specify whether to include archived assets in the suggestions (true) or not (false). Defaults to false.

    • withOtherType: (Optional) add a criterion to include another asset type in the suggestions.

      withOtherType

      By default, we will only look for suggestions on assets of the same type. You may want to expand this, for example, by including View(s) when looking for suggested metadata for Table(s).

    • where: (Optional) add a criterion that must be present in every search result. (NOTE: These are translated to filters.)

    • whereNot: (Optional) add a criterion that must not be present in any search result.

  3. Finally, to retrieve the suggestions, call the .get() method.

  4. The suggestion response contains a list of suggestions for the requested types. You can access specific suggestions by directly referencing the response attributes, such as response.getOwnerGroups() and response.getUserDescriptions().

      Want to find suggestions for ALL types?

      To include all suggestion types (description, owner, tags, and terms), you can directly pass Suggestions.TYPE.all() to the Suggestions:

      Suggestions(includes=Suggestions.TYPE.all())

    • max_suggestion: (Optional) specify the maximum number of suggestions to return. Defaults to 5.

    • include_archive: (Optional) specify whether to include archived assets in the suggestions (True) or not (False). Defaults to False.

    • with_other_type: (Optional) add a criterion to include another asset type in the suggestions.

      with_other_type

      By default, we will only look for suggestions on assets of the same type. You may want to expand this, for example, by including View(s) when looking for suggested metadata for Table(s).
