As discussed in https://issues.redhat.com/browse/SRVLOGIC-178, the Operator will send events to the Data Index for every workflow deployment / undeployment. This information will be used to mark the corresponding workflow definition as available/unavailable by using a "status" field that will be incorporated to the corresponding ProcessDefinition "metadata".

e.g:

{  

   "metadata" : { "status" : "available" } 
}

While the registering of the ProcessDefinition metadata is already supported, modifications were done to internally store the metadata as a JSON value, and also to support Data Index queries by using the metadata.

Interested parties can now query the information with example queries like these:

 
{
  ProcessDefinitions ( where:{metadata: {status:{equal: "available"}}} ) {
    id
    metadata
  } 
  
}


{
  ProcessDefinitions ( where:{metadata: {status: {equal: "unavailable"}}} ) {
    id
    metadata
  } 
  
}
