[jira] [Updated] (FLINK-19083) Remove deprecated DataStream#split

["Aljoscha Krettek (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-19083?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Aljoscha Krettek updated FLINK-19083:
-------------------------------------
    Description: 
{{DataStream#split()}} has been deprecated in favour of using Side Outputs because: 
 - It is less performant, {{split()}} creates and checks against {{Strings}} for the splitting logic
 - Has bugs: see FLINK-5031
 - The semantics of consecutive splits are not very clear in general
 - Side outputs are more general and everything that could be done using {{split()}} can be achieved with side outputs with strictly better performance.
