You can create a custom profiler by adding the required tags, regex entries to
specific columns within your tables. You can evaluate the tags and regex entries to Boolean
values.
On the Profilers page, click Tag
Rules.
On the Tag Rules tab, click New
to create a new profiler tag rule.
Enter the name of the new custom profiler tag rule.
Enter the description for the custom tag rule.
Select the tags to apply to assets
that
match your regex expressions. You can select tags from the drop-down
list
or enter a new value to create a new tag.
New tags that you create here are added with a dp_ prefix in
the list of Atlas tags. For example, if you add a new tag called
credit_card, this tag will be added as
dp_credit_card in Apache Atlas.
Enter the rule for the column name. As you enter the values, regex
name,
and resource names are
auto-populated.
Select the column that is needed for your custom profiler.
Enter the column value for the DSL.
Based on your entry, Cloudera Data Catalog auto-populates values
from the entries already available in the Resources tab.
For more information about behaviors, see Using DSL Grammar.
Click Save and Validate.
In the validation
modal
window,
enter data to validate your custom profiler tag rule.
Ensure
that
you separate each data entry with a new line.
Click Save to create a tag
rule,
then
validate and deploy it later.
