Hi,
I am new to CEP though I made a simple rule which which declares an event as
expires after few milliseconds.
If events are inserted into a stream and at the same time events are
retracted from the stream due to expiration, the application is stuck - Cant
insert any more events and no events are retracted.
declare StockEventWrapper
@role( event )
@expires(10s)
end
rule "Stock Event Buffer Rules"
dialect "java"
when
$stock : StockMotiveFactWrapper(timeAlerted == null)
$sew: StockEventWrapper(this.synonymContainedInTitle == true &&
$stock.stockId == this.stockId ,$stock.motiveTypeId == this.motiveTypeId)
over window:time(24h) from entry-point "STOCK_EVENTS"
then
System.out.println("Creating " + $stock.getStockId() + " " +
$stock.getMotiveTypeId());
modify($stock){
setTimeAlerted(new Date());
}
end
Any known issues? any ideas?
Thanks,
Rod
