nesper - Output snapshot in Esper -


i created std:unique(id) window in esper in

select * mydata.std:unique(id) rate > 0 output snapshot every 60 seconds; 

what expected @ end of every 60 seconds, list of data rows:

  id: 5  rate: 20   id: 2  rate: 45   id: 3  rate: 22 

instead last row (id:3 rate: 22). tried "snapshot all" , did not either.

is there way produce result set of event happened in 60 seconds window unique id - recent ones?
