See ref [1] and [2]. > We should refactor these Java Streams to improve the performance, for both > legacy scheduler and NG schedulers. > cc [~sewen] [~gjy] > [1] [flink code style > guide|https://flink.apache.org/contributing/code-style-and-quality-java.html] > [2] [discussion & performance > test|https://issues.apache.org/jira/browse/FLINK-14735?focusedCommentId=16974209&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-16974209] > which compares the performance. -- This message was sent by Atlassian Jira (v8.3.4#803005)
