Re: Why is monOpenObjectActivity showing high LogicalReads eventhough OptSelectCount & UsedCount are both zero.

Avinash,

     From MDA tables we collect data every minute into staging and summarize them into a hist table to reduce rowcount. Here is what I see in our database showing high reads for IndexID > 0 for Lock scheme Datarows table.

Thanks,

Sid.

select top 10 ObjectID, IndexID, LogicalReads,PhysicalReads,OptSelectCount,UsedCount,LastOptSelectDate,Operations

from monOpenObjectActivityHist

where ObjectName like '%blabla'

and UsedCount + OptSelectCount = 0

order by LogicalReads desc
