You can use a query language with the tDataStewardshipTaskDelete and tDataStewardshipTaskInput components to query and filter the data you want to delete or read from Talend Data Stewardship.

The query statement used to filter tasks on the server is composed of one or several conditions. You can combine or negate conditions using the boolean operators and and or, or the not operator respectively. Parenthesis are supported to override default boolean precedence.

A task condition is composed of a field name, an operator and a value. You should use simple quotes around strings, and precede quotes within the string with a backslash.

Supported metadata fields on tasks are:
