Regarding Flink as a web service

[Sam Hawk]

Hi,

I am new to Flink and I have a very basic question to start with. 

I have started working with some very basic exampes and was wondering we can make the streams available as json(via a rest service) which can be further be used by any front end technology for visualization in the form of charts and graphs.

Any helpful link to the tutorial will be appreciated.

Thanks,

Sam

You could write your data back to Kafka using the FlinkKafkaProducer and then use websockets to read from kafka using NodeJS or other.

There is also queryable state, which allows you to query the internal keyed state of Flink user functions.

There's also a nice documentation page on the feature now: https://ci.apache.org/projects/flink/flink-docs-release-1.2/dev/stream/queryable_state.html
