…rations Reduced the number of cassandra-stress prepare and stress operations from 4 to 2, doubling the workload per command (500K to 1M rows per operation). This consolidation reduces coordination overhead while maintaining the same total dataset size of 244GB (2M rows * 128KB). Optimizations made: - Removed use_legacy_cluster_init from all scale configurations - Reduced stress duration from 180m to 30m for faster iterations - Increased add_node_cnt for faster scale-up (40-60: 1→10, 180-200: implicit→20, 450-500: implicit→50, scale-cluster: 1→5) - Halved n_loaders from 4 to 2 in scale-cluster base config - Maintained cluster_health_check: false for large clusters Files modified: - configurations/scale/scale-40-60.yaml - configurations/scale/scale-180-200.yaml - configurations/scale/scale-450-500.yaml - test-cases/scale/scale-cluster.yaml (cherry picked from commit 533364a)
