[jira] [Commented] (SPARK-5484) Pregel should checkpoint
periodically to avoid StackOverflowError
[ https://issues.apache.org/jira/browse/SPARK-5484?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15311679#comment-15311679 ]
Anderson de Andrade commented on SPARK-5484:
--------------------------------------------
How is this not a priority? If we are not fixing Pregel then let's expose {{aggregateMessagesWithActiveSet}} to users so they can create their own version.

> Pregel-based iterative algorithms with more than ~50 iterations begin to slow down and eventually fail with a StackOverflowError due to Spark's lack of support for long lineage chains. Instead, Pregel should checkpoint the graph periodically.
