Compared to the current approach, where copying happens in multiple stages (filtering, garbage collection, and coalescing), my proposal combines these steps into one. While benchmarks are needed to confirm any performance gains, this method should, at the very least, not perform worse than the existing one That makes sense. This would be a change downstream within Datafusion then correct? -- This is an automated message from the Apache Git Service.
