    Description

      I've been evaluating Nemo's streaming performance by running Nexmark queries. 

      When running Query 7 with 150,000events/s input rate, sometimes Nemo fully consumes CPU resource at some point and throws OOM. This happens intermittently and it looks like a bug. Sometimes Nemo just uses ~50% cpu use constantly and processes the inputs without exception.
