Abstract
Systems and methods are disclosed that perform dynamic database schema modification. A database system may receive a request to change a schema. In response to receiving the request to perform the dynamic schema modification, the database system may complete pending transactions and begin modifying the database schema. Any requests to access the database received prior to completion of the modification may be paused, thereby allowing the database to remain online and continue receiving requests while the modification is in progress. After completion of the modification, the paused requests may be resumed.
