From a query perspective, I guess the AU would have its id and origin information - and the ATs for the AU would have the AU id as a foreign key that could be used to tie them back to the same unit?

ElasticSearch Activity Store implementation ------------------------------------------- Key: RTGOV-415 URL: https://issues.jboss.org/browse/RTGOV-415 Project: RTGov (Run Time Governance) Issue Type: Sub-task Reporter: Gary Brown Assignee: ivan mckinley Fix For: 2.0.0.Final Although it is not currently clear whether organisations would rely on ElasticSearch as a database for their activity information, it will be good to be able to offer it as an alternative. If configured, then it will store the ActivityUnit, and any subsequent EPN can be used to store the derived information (e.g. situations and response times). ElasticSearch has improved its support for backup/restore, so could potentially be used as a primary db for this type of information - although it is not transactional. The module should be defined in modules/activity-management/activity-store-es (or elasticsearch - whatever is consistent with RTGOV-342).
