> Getting the size of a binary value of a MultiBinaryPropertyState reads through the entire stream to determine the length. Depending on the backend store (e.g. S3 datastore), this can be rather expensive. OAK-5205 introduced a size check with NodeDocument.split() on binary properties and may now result in long running background updates.
