Subject Re: Would like to add a connector to DistributedLog.
Date Sun, 29 May 2016 05:37:36 GMT
Hi Jia,

There's currently no dedicated documentation for composing streaming
connectors, but for examples, I would say that the Elasticsearch and Nifi
connectors are a good place to start learning. For a more full blown example
I recommend taking a look at the Kafka connector. Basically, you'll extend
the RichParallelSourceFunction for sources (or RichSinkFunction for sinks)
and implement the required methods that will be called during the source /
sink tasks' life cycle.

I'd be happy to help you with any questions you may come into while
implementing the connector. Also, I'm thinking about adding documentation
for composing a new connector (filed in
https://issues.apache.org/jira/browse/FLINK-3989) as its a frequently asked
question, so any feedback during your learning process will be quite
