User Story (Required on creation):

• I want to fetch available external tasks regardless of their topic name, so I can build a general broker that redistributes the locked tasks, for example via Kafka
• I want to fetch available external tasks based on only a certain fixed part of a topic name. The topics also contain a dynamic part that is not relevant for the worker at the time the tasks are fetched but only when they are worked on.

Functional Requirements (Required before implementation):

• I can fetch external tasks regardless of the topic (either by providing a wildcard topic name, by specifying no topic at all, or by using an "allTopics" option)
• I can fetch external tasks based on a partial topic name including wildcards
• Code example:

  List<LockedExternalTask> tasks = externalTaskService
    .fetchAndLock(10, "worker")
    .topic("*", 30000L)
    .execute();
  

Technical Requirements (Required before implementation):

• Either
  • Allow passing a wildcard character or expression as the topic name, for example: "*" to query for all topics
  • Add a new query option "topicLike" that allows passing a wildcard character or expression as the topic name, for example: "*" to query for all topics

Limitations of Scope (Optional):
