index templates other than logs and metrics when using data streams #751

Problem

In most real world scenarios a user is not in control over the default index templates "logs" and "metrics". There are many usecases where the user wants to define a custom template. In my case I want to use the data retention feature to delete messages stored in elasticsearch after a certain amount of time.

Currently this connector is able to use the predefined index templates "logs" and "metrics" when data streams are enabled. User created templates are not supported yet.

Solution

Defining the type of the data stream as String to make it flexible for custom inputs. The enum will not be removed to still be able to use the recommender when deploying the connector via control-center.

Does this solution apply anywhere else?

• yes
• no

Test Strategy

Started a local cluster via docker-compose (cp-quickstart and elastic+kibana) and installed the connector.zip in the cluster. Both connectors with "logs" and connectors with "custom" as data stream types were running perfectly fine after creating the "custom" index template in Kibana.

Testing done:

• Unit tests
• Integration tests
• System tests
• Manual tests
