I wonder if KSQL support https://docs.confluent.io/current/streams/concepts.html#processing-guarantees
Exactly_once semantic ?
回答1:
KSQL is implemented on Kafka Streams API which means it provides exactly once delivery guarantee, linear scalability, fault tolerance and can run as a library without requiring a separate cluster.
It is stated in Confluent's KSQL: Streaming SQL Engine for Apache Kafka. See last sentence of the abstract.
