INDEX STRUCTURE NAVIGATION USING PAGE VERSIONS FOR READ-ONLY NODES

摘要

Read-only nodes of a distributed database system may implement index structure navigation using page versions. A read request may be received at a read only node of a distributed database for select data. Data pages linked together to form an index structure for data stored for the distributed database may be navigated according to versions maintained for the data pages in order to identify one or more locations to access for the select data. One or more prior versions of data pages may be selected as part navigating the index structure according to a consistent view of the distributed database associated with the read request. Change notifications may also be received at the read-only node modifying the data pages of the index structure. The index structure modifications may be applied without blocking the index structure navigation for servicing the read request.
