DUAL DATA STORAGE USING AN IN-MEMORY ARRAY AND AN ON-DISK PAGE STRUCTURE

摘要

The subject matter disclosed herein provides methods for the dual storage of data using an in-memory array and an on-disk page structure. An in-memory array holding a column of data can be maintained. One or more pages can be maintained. Each of the one or more pages can have one or more rows for storing the column of data. Random access can be provided to a subset of the one or more rows by at least loading the subset of rows from the one or more pages to the in-memory array without loading all of the rows from the one or more pages. Related apparatus, systems, techniques, and articles are also described.

1. A method for implementation by one or more data processors forming part of at least one computing system, the method comprising:
maintaining an in-memory array holding a column of data; maintaining one or more pages, each of the one or more pages having one or more rows for storing the column of data; and providing random access to a subset of the one or more rows by at least loading the subset of rows from the one or more pages to the in-memory array without loading all of the rows from the one or more pages.
