Hello! I've read about the KSQL streaming SQL for Kafka. In my opinion, this is a big step for performing complex event processing on streams.
In the provides examples there is a TUMBLING window function. By default, I assume that the windowing is performed on the timestamp generated by the system. I would like to know, if there is any support in KSQL to perform window function a custom field from the message ( for example timestamp or any field that contains time format). I look forward for your answers. Best regards, Florin
