Hi, We have a keyed pipeline with persisted state. Is there a way to broadcast a command and collect all values that persisted in the state ?
The end result can be for example sending a fetch command to all operators and emitting the results to some sink why do we need it ? from time to time we might want to check if we are missing keys what are the additional keys or simply emit the current state to a table and to query it. I tried simply broadcasting a command and addressing the persisted state but that resulted with: java.lang.NullPointerException: No key set. This method should not be called outside of a keyed context. is there a good way to achieve that ? Cheers Avi
