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?
