MANAGING LARGE DATA SETS THROUGH PAGE BASED INFORMATION TRACKING IN MULTI-MASTER ENVIRONMENTS

摘要

A data store receives a page cookie as a request for a page of records. The page cookie acts as a container to a record identifier of a last retrieved record and a timestamp of the last change to the record. The data store identifies retrieved pages to skip over according to a comparison of date, time and data instance name / write-master information for each record in the retrieved pages against the information in the page cookie. The data stamp contains information about the timestamp of last change to the record and data store instance name of the record. Subsequent to finding a matching record, the data store creates a new page cookie based on the page containing the record and transmits the new page cookie and the page to the requester.
