Hi all, We hope to deprecate current Statistics implementation of DAS REST API from the APIM 2.0.x version. The reason was, when compared with RDBMS implementation REST client having a comparable performance issue. We did a performance test for both REST and RDBMS implementation and we observed the following result.
records RDBMS (ms) REST (ms) 10 42 89 20 10 110 30 10 120 40 9 150 50 15 160 100 9 350 200 12 1100 350 10 1466 1000 33 2306 2000 8 7351 3000 11 11381 4000 14 20504 5000 9 29633 Thus comparing numbers, we can see that in REST client implementation there is a huge performance issue compared to RDBMS. Thus APIM default analytic client will be RDBMS instead of REST client from APIM next release onward and REST implementation[1] will be deprecated.
