[jira] [Commented] (SPARK-16900) Complete-mode output for file
sinks
[ https://issues.apache.org/jira/browse/SPARK-16900?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15414455#comment-15414455 ]
Vladimir Feinberg commented on SPARK-16900:
-------------------------------------------
Alternatively, if we could have some way of altering the aggregation sinks to have versioned append-mode output that'd be just as good

> Currently there is no way to checkpoint aggregations (see SPARK-16899), except by using a custom foreach-based sink, which is pretty difficult and requires that the user deal with ensuring idempotency, versioning, etc.
