摘要:
The embodiments described herein relate to accessing a plurality of data elements. A page of column data is compressed and stored in a format that includes a collection of data elements. A tuple map is stored, and the collection of data elements is indexed via the tuple map. A query is processed based on the compressed page by identifying a set of tuple identifiers mapping to stored data in support of the query. Each tuple identifier corresponds to a location of a respective tuple of the compressed page.
