Hi Team,
We have few queries which were running good until last week; but for the past 3 days these queries were facing severe some performance issues and timeout dumps in the back-end.
For some selections it is running long and for some selection it is executing quicker and for some selection it is getting time out.
We made a complete data rebuild for the queries connected data targets (data rebuild from the source) before 3 days; after which the query performance issue faced.
No changes were made to the queries or objects for the last 2 months.
Data Flow - Query -> Multi Provider -> Infoset -> InfoCube -> DSO -> Datasource (DB Connect).
Note:
In Query we have nested aggregation to handle the result rows; but again no changes to it for the past 2 months.
We have loaded data in one single request at the InfoCube level.
I mean some 2 million records with different plants in one single request do it have performance impact while reading data?
Can anyone please throw light on the possible cause for the performance issue?
Thanks
Regards
San
