Hi,

That was really informative messages. Thank you very much sharing.

I’ve created NonClustered Index (IDX_x) and COLUMNSTORE INDEX (idx_csi).

Once I run SELECT query with NonClustered Index, the query takes 30 secs to execute and COLUMNSTORE INDEX takes around 2 seconds to execute.

But, if I try to run the NonClustered Index once again, surprisingly it takes only 2-3 seconds to run the query. So my question is once COLUMNSTORE INDEX is created and ran, is there any mechanism which stores the searched data in memory and will be used later if required. Let me know how it works.

Thanks,

Santosh
