---------------------------------------

             Summary: event resiliency
                 Key: QUARKS-192
                 URL: https://issues.apache.org/jira/browse/QUARKS-192
             Project: Quarks
          Issue Type: Improvement
            Reporter: Jerome Chailloux


Assuming that I have a Raspberry Pi that ingest data and doing some aggregate.
I have to send information to Watson IoT.

What if if I lost the network ?
Could we have a mechanism that send data at all time and if network is not available store
all events in a file ?
As soon as the network is available again play back the file and send new events.
We have to be sure that all events are sent in the correct order from file to "real time".

The computation engine (IBM Streams in this case) will then apply some policies to deal with
or not with out of order events for the real time computation but at least able to store data
received from sensors.


Any idea about how to achieve this ?
