This makes the key unpredictable if we support features such as reloading a pipeline with a new SDK or bugfixed pipeline. The encoding should be stable and documented. > And even if the SDK's window types are stable and documented, users can define their own windows with coders and these may be less stable / requiring bugfixes. This ticket is to track the issue and any new ideas. > [1] https://github.com/apache/incubator-beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/util/state/StateNamespaces.java#L113 -- This message was sent by Atlassian JIRA (v6.3.4#6332)
