Summary: Add pure-API Watermark class Key: FLINK-12587 URL: https://issues.apache.org/jira/browse/FLINK-12587 Project: Flink Issue Type: Improvement Components: API / DataStream Reporter: Aljoscha Krettek Assignee: Aljoscha Krettek Currently, {{Watermark}} extends {{StreamElement}}, which comes with a lot of transitive dependencies to classes and modules that are runtime code and shouldn't be in an API package. In the future, we want to more clearly separate API packages from runtime packages. The first instance of this is trying to put {{TableSources}} into {{flink-table-common}}, which will require our source-like interfaces to be clean of runtime dependencies. This means that we have to put {{SourceFunction}} into {{flink-core}}, which has {{Watermark}} in its interface, which we therefore have to untangle from runtime classes. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
