Flink Jira Bot updated FLINK-7018:
----------------------------------
Labels: auto-unassigned pull-request-available stale-major (was:
auto-unassigned pull-request-available)
I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help
the community manage its development. I see this issues has been marked as
Major but is unassigned and neither itself nor its Sub-Tasks have been updated
for 30 days. I have gone ahead and added a "stale-major" to the issue". If this
ticket is a Major, please either assign yourself or give an update. Afterwards,
please remove the label or in 7 days the issue will be deprioritized.
> Refactor streamGraph to make interfaces clear
> ---------------------------------------------
>
> Key: FLINK-7018
> URL: https://issues.apache.org/jira/browse/FLINK-7018
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Reporter: Xu Pingyong
> Priority: Major
> Labels: auto-unassigned, pull-request-available, stale-major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Motivation:
> 1. StreamGraph is a graph consisted of some streamNodes. So virtual
> nodes (such as select, sideOutput, partition) should be moved away from it.
> Main iterfaces of StreamGraph should be as following：
> addSource(StreamNode sourceNode)
> addSink(StreamNode sinkNode)
> addOperator(StreamNode streamNode)
> addEdge(Integer upStreamVertexID, Integer downStreamVertexID,
> StreamEdge.InputOrder inputOrder, StreamPartitioner<?> partitioner,
> List<String> outputNames, OutputTag outputTag)
> getJobGraph()
> 2. StreamExecutionEnvironment should not be in StreamGraph, I create
> StreamGraphProperties which extracts all env information the streamGraph
> needs from StreamExecutionEnvironment. It contains:
> 1) executionConfig
> 2) checkpointConfig
> 3) timeCharacteristic
> 4) stateBackend
> 5) chainingEnabled
> 6) cachedFiles
> 7) jobName
>
> Related Changes:
> I moved the part of dealing with virtual nodes to
> StreamGraphGenerator. And get properties of StreamGraph from
> StreamGraphProperties instead of StreamExecutionEnvironment.
>
> It is only a code abstraction internally.
