Wilmer DAZA commented on FLINK-2151: ------------------------------------ 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 > Provide interface to distinguish close() calls in error and regular cases > ------------------------------------------------------------------------- > > Key: FLINK-2151 > 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}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
