Abstract
A computing system concurrently executes a builder thread and a reader thread. The builder thread modifies a document by modifying an active representation of the document. The reader thread perform operations regarding the document using a non-active representation of the document. The active representation of the document and the non-active representation of the document are stored in a memory of the computing system. The active representation of the document and the non-active representation of the document do not include different copies in the memory of the same data. When reading data in the non-active representation of the document, logical consistency is ensured without locking any data in the non-active representation of the document.
