System roles could be added with https://github.com/RedHatInsights/rbac-config to stage/production where teams adds their roles.

During seed process when new system's roles are being added - kafka message is produced for each tenant(orgs). Currently there is more than 100k orgs - it means that same count of kafka messages is being produced which leads to performance implications.

We need reduce count of produced message at one time during seed process.

Solutions:

1.

One solution could be to divide produced messages to batches.

It introduces delay when notification would be delivered - we need to find whether this is acceptable.  rhn-support-rabbott ?

2. 

Is it possible to filter orgs who has subscripted notification for such event type by some notification API ? Probably it needs to confirm how many tenants(orgs) has subscripted this option now. (event_types =
rh-new-role-available, rh-platform-default-role-updated, rh-non-platform-default-role-updated) glepage@redhat.com
