on high cardinality dim filters and metric sorting use case can not be multiengine query, has to be single engine query

[pranavbhole]

When there is dim filtering on campaign name field and metric sorting, then multiengine use case prefers metrics sorting over dim filtering and query returns inconsistent results.

Fix: Ideally for dim filters other then status,id (high cardinality filters), and metrics sorting use case should go to oracle only. This case can not be multiengine use case.
