Hello Haribabu, Thank you for the performance test. But please not that the patch is 'thrown away', and will be totally rewritten. I have no idea of the status of the second / third attempt however. However, what is interesting is that for some queries this patch is already on par with VCI. Which db is that exactly?
Alvaro, You wrote that a wiki page would be opened regarding this. But I still cannot find such a page (expect for an old page which hasn't changed in the last year). Is there already something we can look at?
