Is KSQL ANSI SQL compliant?

Explanation:
KSQL is a SQL-like language designed for streaming data on Apache Kafka. ANSI SQL, on the other hand, is designed for relational databases and batch queries. The key difference is that KSQL operates on continuous streams, with time-based windows, and uses streams and tables as first-class concepts, with Kafka topics as inputs. These streaming-specific features—continuous queries, windowed aggregations, and stream-to-stream or stream-to-table joins—have no direct, standard equivalents in ANSI SQL. So, while the syntax may look familiar, the execution model and semantics are different, meaning KSQL is not ANSI SQL compliant.
