Abstract
Techniques related to accelerated detection of matching patterns are disclosed. In an embodiment, a method may involve, for a single field of a body of records, contiguously storing field values, thereby storing the field values as a concatenation. The method may also involve identifying a match in the concatenation that matches a value pattern specified by a value pattern expression. The value pattern may include a first partial pattern and a second partial pattern. Further, the method may involve determining that the match is contained in a single field value of the body of records. Still further, the method may involve establishing the match as a matching value. The match may be determined to be contained in the single field value based on searching a data structure comprising length information or offset information for a subset of the field values stored as the concatenation.
