QUERY SUMMARY GENERATION USING ROW-COLUMN DATA STORAGE
摘要
A data storage system (122) includes a column store (281) and a row store (282). The data storage system (122) may generate a query summary. The data storage system (122) determines query summary fields comprised of a subset of fields from a schema used to store data in the row store (282). The data storage system (122) searches the column store (281) or the row store (282) for query results in the query summary fields. A query summary field is generated from the query results in the query summary fields.
