Is there a way to see what you have sent out in a Broadcast? I am unable to tell what I have sent.
There is no such feature in Spark. Although this is a highly requested feature https://issues.igniterealtime.org/browse/SPARK-1051 . But Spark doesn’t have active experienced developers currently to work on such complex things (sending a broadcast to 100 users would need to write that message into 100-200 history files on the sending side, which may crash or hang Spark if not done correctly).
