[jira] [Commented] (SPARK-8834) Throttle DStreams dynamically
through back-pressure information
[ https://issues.apache.org/jira/browse/SPARK-8834?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14614777#comment-14614777 ]
François Garillot commented on SPARK-8834:
------------------------------------------
More feature-rich, in that (see design doc) this offers:
- an API for the computation of a maximum rate of ingestion
- an extension in the form of [SPARK-8835|https://issues.apache.org/jira/browse/SPARK-8835], the second part of [SPARK-7398|https://issues.apache.org/jira/browse/SPARK-7398]
