I've been trying to find this on cisco.com but could not find an explicit statement.
When quering db_cra seems all tables not starting by rt are historical. Historical data seems to have 2 hours delay from the queries results at least for ContactQueueDetail and ContactCallDetail.
Is it correct to assume that historical tables are written 2 hours after the contacts have been completed or am I missing something? Is this at all configurable? We are trying to get SLA and total calls in real-time for our custom wallboard.
The writing interval for Real-Time seems configurable from real time snapshot config and set to default 30 seconds. what would be the impact for a small call center of getting this value lower and what would be the number we should not to go under?
