Seems I've got what you’re talking about. I’ve tried to change the root directory (*persistencePath*) and saw that only data/indexes were placed to it while wal stayed somewhere in my work dir. It works counterintuitive and causes non productive discussions like we are in arguing about *persistencePath* or *storagePath*. Neither name fits this behavior.
My suggestion will be the following: - *persistencePath* refers to the path of all storage files (data/indexes, wal, archive). If the path is changed *all the files* will be under the new directory unless *setWalPath* and *setWalArchivePath* are set *explicitly*. - *setWalPath* overrides the default location of WAL (which is setPersistencePath) - *setWalArchivePath* overrides the default location of the archive (which is again has to be setPersistencePath). If we follow this approach the configuration and behavior becomes vivid.
