Fabian Hueske commented on FLINK-10871: --------------------------------------- This proposal would change the semantics of these methods. Right now, I cannot assess the impact of the change. I think we can discuss it for the Table API, it won't be possible to apply the change to DataSet and DataStream API without breaking backwards compatibility. > ExecutionEnvironment & TableEnvironment should be singleton > ----------------------------------------------------------- > > Key: FLINK-10871 > URL: https://issues.apache.org/jira/browse/FLINK-10871 > Project: Flink > Issue Type: Improvement > Reporter: Jeff Zhang > Assignee: Hequn Cheng > Priority: Minor > > For now, ExecutionEnvironment.getExecutionEnvironment and > TableEnvironment.getTableEnvironment will always create a new object, I don't > think singleton should be sufficient for flink app unless I misunderstand it. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
