Victor Dogaru commented on QUARKS-192:
--------------------------------------
There are currently an in-memory and a file-based repository [1]. Having
pluggable repositories might facilitate integration on embedded systems with
custom storage.

> 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 ?
