Regarding Flink as a web service

[Sam Hawk <dj...@gmail.com>]

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

There's also a nice documentation page on the feature now:

+uce@apache.org <uc...@apache.org> Because he implemented queryable state.

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

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