text: Title: LOG.old files
  Body: ## ❓Question
  I am using an [aimlflow](https://github.com/aimhubio/aimlflow) watcher to sync aim with mlflow every minute and I found out that the repository size get's quite big (1gb for a run with ~2e5 logged metrics) because of an abundance of LOG.old files inside the meta/chunks/run_id folder.
  Are these necessary, can I remove them or prevent them from being stored?
