# left-join-on-timeout

Kafka Streams left join on timeout

## Usage

Eliminates the lack of sql-like left join semantic in kafka streams framework.

This implementation will generate left join event 

only if full join event didn't happen in join window duration interval.

The main idea behind the scene is to schedule left joined event on left stream and cancel it on full joined stream.
