Abstract
Systems and techniques of the management of the metadata of a database are presented. A provider is in communication with a database and a set of consumers of the database. Data may be changed by addition, editing or deletion from the database and such changes are recorded and/or maintained by the provider on a list of changes. The changes on this list may be associated with a sync token. The provider may also maintain a list of consumers and associate with each consumer a last sync token which describes when the last sync request and update on the database was made with the consumer. Data which is deleted from the database is recorded with a tombstone. The tombstone is maintained on the list of changes until all consumers have been made aware of the deletion—then the tombstone may be deleted from the list of changes.
