US11449551B2	Handling out-of-order data during stream processing and persisting it in a temporal graph database The present technology addresses deficiencies associated with common practices for handling out of order data in a streaming data database.

If there is also data in the database for a time earlier than the timestamp of the out of order data, the earlier data is adjusted so that its next modification time matches the timestamp of the out of order data.
