How to get parent's child instances?

[rairafaqatali]

Hi @sfmskywalker
I have a parent workflow that triggers the child workflow.

Is there any mechanism where I can fetch all the child instances of parent workflow?

Hi @rairafaqatali ,

Unfortunately there is no relationship being maintained between a parent and a child workflow.

What we could do to support this is add a new property to WorkflowInstance called CustomAttributes which would be a simple dictionary of string/object pairs.

Then the RunWorkflow activity could set its own instance ID as the parent ID of the child workflow instance.
To make this searchable, we would also introduce a new table called something like WorkflowInstanceAttributes.

This enables other scenarios as well, where you want to associate more custom data with a given workflow and search for workflow instances by a given value.
