Does anyone know what QDS_SHUTDOWN_QUEUE Wait type is in SQL Server 2014? All I can find it is related to query store package and that it can be ignored by it is the top wait on this server. The only thing running on this server is a job that restores 196 full/diff backups, performs DBCC CHECKDB then drops the database.The job is now taking twice as long as it was taking last week. I've disabled the DBCC CHECK step which appears to be what's causing it to take longer and noted some improvement but I'm curious about this particular wait and DBCC CHECKDB. Does anybody know?WaitType QDS_SHUTDOWN_QUEUEWait_Sec 44402.37Resource_Sec 44401.28Signal_Sec 1.1Wait Count 741Wait Percentage 64.85AvgWait_Sec 59.9222AvgRes_Sec 59.9208AvgSig_Sec 0.0015
