I’m afraid I don’t understand your point: I am not trying to compare Flink to Proton’s docker image sizes; nor do I see how it is relevant. In this case, they are clearly talking about the size of the binary as in “executable of the software you can download”. Both the OP and myself are surprised that a 500MB binary is considered “lightweight”, probably because -even in 2024- “lightweight” should probably still be around the tens of MBs at most.
