[jira] [Commented] (MAHOUT-1755) Mahout DSL for Flink: Flush intermediate results to FS

    [ https://issues.apache.org/jira/browse/MAHOUT-1755?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14602109#comment-14602109 ] 

Dmitriy Lyubimov commented on MAHOUT-1755:
------------------------------------------

but pipelines could be translated to a flink graph, right? that way somethign like rowSums() or dfsWrite() (or nrow) would truly trigger Flink graph execution. The action is deffered, right?

> Now Flink (unlike Spark) doesn't keep intermediate results in memory - therefore they should be flushed to a file system, and read back when required.
