> Based on the related discussion on the dev email list, the QuestDB handling of the metrics repository needs to be improved to have better fault tolerance in order to be possible to use as a viable option for default metrics data store. This should primarily focus on handling unexpeted database events like corrupted database or loss of space on the disk. Any issues should be handled with an attempt to keep the database service healthy but in case of that is impossible, the priority is to keep NiFi and the core services running, even with the price of metrics collection / presentation outage.
