Couchbase 6, N1SQL Order by desc is taking long time

Thank you vsr1. This Index Advisor helped me lot. It has given me the below index for my sql which solved performance issue.

CREATE INDEX myindex ON mybucket(type,status,startTimestamp DESC,id,subStatus,interaction,endTimestamp,failureReason,traceID,accountNumberToken,customerID,pcn,name) WHERE ((type = “TYP”) and (status = “FAILED”)) WITH { “num_replica”:1 }
