Hi Zeppelin users and developers, The roadmap we have published at https://cwiki.apache.org/confluence/display/ZEPPELIN/Zeppelin+Roadmap is almost 9 month old, and it doesn't reflect where the community goes anymore. It's time to update.
Based on mailing list, jira issues, pullrequests, feedbacks from users, conferences and meetings, I could summarize the major interest of users and developers in 7 categories. Enterprise ready, Usability improvement, Pluggability, Documentation, Backend integration, Notebook storage, and Visualization. And i could list related subjects under each categories. - Enterprise ready - Authentication - Shiro authentication ZEPPELIN-548 <https://issues.apache.org/jira/browse/ZEPPELIN-548> - Authorization - Notebook authorization PR-681 <https://github.com/apache/incubator-zeppelin/pull/681> - Security - Multi-tenancy - Stability - Usability Improvement - UX improvement - Better Table data support - Download data as csv, etc PR-725 <https://github.com/apache/incubator-zeppelin/pull/725>, PR-714 <https://github.com/apache/incubator-zeppelin/pull/714>, PR-6 <https://github.com/apache/incubator-zeppelin/pull/6>, PR-89 <https://github.com/apache/incubator-zeppelin/pull/89> - Featureful table data display (pagenation, etc) - Pluggability ZEPPELIN-533 <https://issues.apache.org/jira/browse/ZEPPELIN-533> - Pluggable visualization - Dynamic Interpreter, notebook, visualization loading - Repository and registry for pluggable components - Improve documentation - Improve contents and readability - more tutorials, examples - Interpreter - Generic JDBC Interpreter - (spark)R Interpreter - Cluster manager for interpreter (Proposal <https://cwiki.apache.org/confluence/display/ZEPPELIN/Cluster+Manager+Proposal> ) - more interpreters - Notebook storage - Versioning ZEPPELIN-540 <http://issues.apache.org/jira/browse/ZEPPELIN-540> - more notebook storages - Visualization - More visualizations PR-152 <https://github.com/apache/incubator-zeppelin/pull/152>, PR-728 <https://github.com/apache/incubator-zeppelin/pull/728>, PR-336 <https://github.com/apache/incubator-zeppelin/pull/336>, PR-321 <https://github.com/apache/incubator-zeppelin/pull/321> - Customize graph (show/hide label, color, etc) It will help anyone quickly get overall interest of project and the direction.
