Does [this](https://discuss.elastic.co/t/how-to-split-into-multiple-events-dynamically-for-a-given-json-tried-from-various-question-in-forums/167745/10) help? If you are splitting on a very large field then the split filter clones the target field before overwriting it. Obviously that can be optimized to remove the target before cloning it.
