Ingnite.Net ContinuousQuery

["Coleman, JohnSteven (Agoda)" <Jo...@agoda.com>]

I'm trying to get a continuous query running to update an entry when its put in the cache with a 0 status.

A producer thread populates the cache, and this thread (code below*) should do the job but nothing happens, no listener or filter activity at all. I'm wondering if this task is even connected to the same cache instance? Where should computing logic for the continuous qry go, its same as the initialQry?

Thanks,
John

     var eventListener = new EventListener();
            var qry = new ContinuousQuery<int, SimpleTransaction>(eventListener);
            var initialQry = new ScanQuery<int, SimpleTransaction>(new InitialFilter());
            using (var queryHandle = _cache.QueryContinuous(qry, initialQry))
            {
                foreach (var entry in queryHandle.GetInitialQueryCursor())
                {
                    var simpleTransaction = entry.Value;
                    ComputeFees(simpleTransaction);
                    simpleTransaction.EventStatus = 1;
                    _cache.Put(simpleTransaction.Id, simpleTransaction);
                    Console.WriteLine("computed: " + simpleTransaction);
                }
            }

Hello!

I think you are going to close this Continuous Query when leaving using()
block, so it will not get any updates. Avoid closing ContinuousQuery while
it is needed.
