Bulk lists

Bulk lists

Overview

Bulk lists let you build block lists and allow lists. Compared to lists in expressions, bulk lists support a much bigger scale and let you reuse the list across workflows.

Create a bulk list

To create a bulk list, simply give it a name and description. You can then add or delete strings as list items.

Look up a bulk list

To find if a value matches the bulk list, first create a list lookup step under a data source stage. You can choose between case-sensitive and case-insensitive match types. For the lookup value, you can use any expression to output a string.

The list lookup step will output a boolean for the match result. You can access it in subsequent stages under the sources namespace, e.g., sources.is_blocked_country.

The list look step won’t be mocked in sanity tests or backtests.
