Hi, in one of our systems, we added a kind of pagination feature, that shows N records of Total records.
To do this, we added a "count(*) over() as Total" field in our queries in replacement of doing two queries, one for fetching the records, and other for getting the count. This improved the performance, but we are't happy with the results yet, by removing the count, the query takes 200ms vs 2000ms with it.
We are thinking of removing the count, but if we do that, the system will lack an interesting feature.
What strategy for showing the total number of records returned do you recommend?.
