Subject [jira] [Commented] (FLINK-3118) Check if MessageFunction implements ResultTypeQueryable
Date Sat, 05 Dec 2015 13:11:10 GMT

    [ https://issues.apache.org/jira/browse/FLINK-3118?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15043304#comment-15043304

Chesnay Schepler commented on FLINK-3118:
-----------------------------------------

that would mean skipping the input validation for all functions that implement ResultTypeQueryable.

Now i don't know anything about the Graph API, but why can't you get the input type from the
input datasets?

> To generalize message values in vertex centric computations, it is necessary to let the
user define the {{TypeInformation}} via {{ResultTypeQueryable}}. This needs to be checked
in {{VertexCentricIteration}}.
