Thanks Chesnay for raising this discussion thread. I think there are 3 major use scenarios for flink binary distribution.
1. Use it to set up standalone cluster 2. Use it to experience features of flink, such as via scala-shell, sql-client 3. Downstream project use it to integrate with their system I did a size estimation of flink dist folder, lib folder take around 100M and opt folder take around 200M. Overall I agree to make a thin flink dist. So the next problem is which components to drop. I check the opt folder, and I think the filesystem components and metrics components could be moved out. Because they are pluggable components and is only used in scenario 1 I think (setting up standalone cluster). Other components like flink-table, flink-ml, flnk-gellay, we should still keep them IMHO, because new user may still use it to try the features of flink. For me, scala-shell is the first option to try new features of flink.
