> TriggerExecutor doesn't currently group mutations returned by triggers even if belonging to the same row key: while harmless per se (at least, I think so), this is definitely a performance problem, because each mutation is a *cluster* mutation, generating more network traffic, more disk IO and more index calls (if present).
