------------------------------------
Hello guys
I was wondering if there is already a plan to integrate Flink with Cassandra?
(read/write tables, send queries en CQL, etc).
I am more interested in writing to cassandra tables from the Stream API of
Flink, but i guess that an integration would require not just writing from
DataStream but a whole complete connector with many other common functionalities
I am making this comment here because I'm guessing that maybe some work in such
a connector may be already started.
Thank you

> URL: https://issues.apache.org/jira/browse/FLINK-2151
> Project: Flink
> Issue Type: Improvement
> Components: Local Runtime
> Affects Versions: 0.9
> Reporter: Robert Metzger
>
> I was talking to somebody who is interested in contributing a
> {{flink-cassandra}} connector.
> The connector will create cassandra files locally (on the TaskManagers) and
> bulk-load them in the {{close()}} method.
> For the user functions it is currently not possible to find out whether the
> function is closed due to an error or an regular end.
> The simplest approach would be passing an additional argument (enum or
> boolean) into the close() method, indicating the type of closing.
> But that would break all existing code.
> Another approach would add an interface that has such an extended close
> method {{RichCloseFunction}}.
