Hi,
I think we dont need to store driver data in SSD as its a transient info, in worst case if the server holding it dies, we will again get all this data in 3 seconds, the consumer of this data, notification and quad tree,will miss some updates, but its fine. we can just push these updates to the queue which can be consumed by notification service and then we can see if the last update of this driver was sent to quad tree 15 second ago then send to quad tree also.we should not store transient information.it is waste of resources
