Reorganizing a data table to improve analytical database performance

摘要

Reorganizing a data table to improve analytical database performance is presented. Attribute value information for data blocks of the data table is determined. One or more queries having respective query predicates involving the attribute may be received and processed. Data blocks having attribute value information matching a query predicate are selected. The selected data blocks are evaluated for the query predicate of the query. For each part of a set of the parts a false positive rate may be determined. The false positive rate may indicate the fraction of data blocks of the selected data blocks of the part, that each contains less than a determined maximum number of rows that satisfy the query predicate. In response to determining for each part of the set of the parts that the determined false positive rates of the part meet a predefined condition sorting the part by the attribute.
