epl - End of File detection in ESPER -

-

i using esper read events csv file. how can make query output when reading csv file finished.

for example want output every 30 min or @ end of file

select id stream output every 30 min or [ eof reached ]

thanks in advance regards

the "adapter.start()" finishes when csv file done , code can send eof event engine. declare context ends on eof event , there "output every 30 minutes , when terminated" option.
