Parameter Sensitivity

We measure parameter sensitivity across the nine queries by varying the window size and slide interval around the baselines in Section "Queries". Each query runs for 30 seconds under 4 vCPU / 8 GB, using the TCP workload of 20k events/s. We test both the sliding and tumbling versions of each query. For originally tumbling queries (Q1, Q6–Q9), we added a sliding variant at the baseline size with a 1 s slide, and for sliding queries (Q2–Q5), we added a tumbling variant at the baseline size. For tumbling queries (Q1, Q6–Q9), we test sizes 5/10/20 s, and for sliding queries (Q2–Q5), we sweep window sizes (Q2: 5/7/10/20 s; Q3/Q4: 5/10/20 s; Q5: 15/45/90 s) and slide intervals (Q2–Q4: 10 ms/100 ms/1 s; Q5: 1/5/10 s).
