Chesnay Schepler updated FLINK-3524:
------------------------------------
Description:
(I don't want to include this into 1.0.0)
Currently, there is no standardized way of parsing JSON data from a Kafka
stream. I see a lot of users using JSON in their topics. It would make things
easier for our users to provide a serializer for them.
I suggest to use the jackson library because we have that aready as a
dependency in Flink and it allows to parse from a byte[].
I would suggest to provide the following classes:
- JSONDeserializationSchema()
- JSONDeKeyValueSerializationSchema(bool includeMetadata)
The second variant should produce a record like this:
{code}
{"key": "keydata",
"value": "valuedata",
"metadata": {"offset": 123, "topic": "<topic>", "partition": 2 }
{code}
