This preview release showcases the per-predicate mutation pipeline feature. This feature increases mutation performance for write heavy processes under certain conditions. See the PR for more information.
IMPORTANT
A feature flag enables this functionality: --feature-flags="mutations-pipeline-threshold=N" — N=0 disables the pipeline entirely (legacy path), N=1 always uses it, N>1 only routes mutations with ≥ N edges to it. The pipeline pays a per-predicate goroutine spin-up cost, so tiny mutations are slightly slower on it; bulk multi-predicate mutations are faster (crossover ≈ 100 edges in in-process benches; live-loading the 1M dataset is ~1.5× faster end-to-end at threshold=1 vs. legacy). As shipped, the current setting is 1, meaning always ON. It's recommended that for your testing you set the value to somewhere around 100.
