I wanted to confirm if there were any known issues where a namespace could be deleted from temporal?
In our production system today our workflows started failing and the issue was due to the default namespace being deleted from cassandra. All of the history data for the previously run workflows was still available via the web frontend, however, when clicking on the “Settings” or “Archival” tab’s nothing displayed. Once I re-created the namespace via tctl the issue was resolved.
Has anyone else encountered this issue before or know of specific issues between temporal & cassandra that may cause this scenario to occur?
