Unfortunately, I think I have to vote -1 (binding) on this RC. During my validation, I ran several tests, especially performance related tests. One of those tests was around performance of the new Stateless Execution Engine. While I didn’t expect a big difference in performance between running a flow in Standard vs. Stateless Execution Engine, I actually saw a huge difference - about 5x better throughput on Standard vs. Stateless. Looking into it showed that the time was all spent in the Provenance Repository, which is odd given that both engines should push the same basic events to the repository. But it turns out that when run in stateless we create a huge number of duplicates. I filed NIFI-13929 [1] to address this.
Given the prominence of the new Stateless feature and the criticality of the issue I’m going to vote -1. I’ll begin looking into a remedy.
