Pattern recognition in data processing, particularly for detecting anomalies and sequences, has been enhanced in SQL with the introduction of the MATCH_RECOGNIZE syntax, part of the SQL standard since 2016. This syntax allows users to write efficient SQL queries to address pattern recognition problems, applicable in both batch and real-time contexts. A blog post from DeltaStream explores using MATCH_RECOGNIZE within the DeltaStream SQL syntax to identify bus trips with significantly increasing delays, offering a detailed breakdown of a sample query. The process involves creating a stream with projected fields, partitioning and ordering data by specific criteria, and defining patterns with variables (A, B, C) for which conditions must be satisfied, such as increasing delays. The MATCH_RECOGNIZE syntax, while initially complex, is demonstrated to be a powerful tool for real-time data analysis and pattern detection.
