The current query run time limit is 2 minutes on the server - sufficient for most reporting needs whilst preventing performance issues associated with "runaway" queries. Time to update the report list Status may be longer if there is significant concurrent server processing, and is also be influenced by network communications latency between the server and the requestor's web browser. If the run time limit is exceeded, the report run will stop and be marked as Failed in the report list. This may happen with queries that would return excessively large result sets , for instance a query with unconstrained scope that returns everything below a high-level concept. |
