Hi Omar,

@Jark I think we could aim to introduce the new Java DSL API in 1.9 and
once we do that we could deprecate the string approach.

.within(Time.seconds(10))
and work only with the timed out matches. Another option is you can try
implementing that logic with ProcessFunction[2]

a deterministic way of generating ElasticseachId this
semantic should be enough for you though. Any duplicates(by the id)
should be updated on the ES side.

ones cause Watermarks might get generated after different

It is definitely a solution ;)
You should be aware of the downsides though:
* you might get different results in case of reprocessing
* you might drop some data as late, due to some delays in processing,
if the events arrive later then the "ProcessingTime" threshold

Hi Averell,
BroadcastState is a special case of OperatorState. Operator state is
always kept in-memory at runtime (must fit into memory), no matter what
state backend you use. Nevertheless it is snapshotted and thus fault
tolerant.

Hi Daniel,
The answer to you original question is you can just keyBy[1] by e.g. the
machineId and then computations on KeyedStream are applied independently
for each key.

Hi,
AFAIK it clashes with
def map[R: TypeInformation](mapper: MapFunction[T, R]): DataStream[R]
if you use partially applied function. You can check the discussion
behind the OnDataStream implementation in this jira[1].

Hi Ramya,
I think the problem is that you access the serializationSchema from the
closure of ElasticsearchSinkFunction. Try creating
ElasticsearchSinkFunction that will get the serializationSchema in ctor.
If this is not the problem could you share the full stack of the error?

Hi,
The path of a savepoint is a user specified parameter, therefore it is
not tracked by flink. It is up to the user to know where should the
savepoint end up.
As for API to check status of a savepoint you can use[1]
