I have another question about stream filters:
1) write item with data format XY to stream
2) enable new stream filter which will now reject new items with format XY
3) write another item with format XY --> will be rejected by stream filter
4) liststreamkeyitems --> returns also data with format XY
regarding 4) why is this the case? I thought that data with format rejected by a stream filter is not returned when reading?
So is a stream filter not applied when reading but only when writing to validate items?
Can you please clarify that?
