Hi Asok,
Siddhi query you are using is wrong. Correct query is
from topkeventstream#window.custom:topKfrequency("3","1",symbol)
select symbol
insert into topkresultstream;
Please refer [1] to learn about Siddhi query language.
When you want to send data out of the window execute
nextProcessor.process(event). It will send particular set of events to the
next execution element of the query(ex: Selector)
