MATERIALIZING DATA FROM AN IN-MEMORY ARRAY TO AN ON-DISK PAGE STRUCTURE

摘要

The subject matter disclosed herein provides methods for materializing data from an in-memory array to one or more pages. 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. At least one of the one or more pages can be marked for materialization. The column of data can be materialized by copying the data from the in-memory array to the one or more rows of the one or more pages. The materializing can be based on the marking. Related apparatus, systems, techniques, and articles are also described.
