Hi Christo, I have tried the following:
- When app starts, I stream into PARTITIONED CACHE one (1) table needed for the distributed jobs - Now when a Task is submitted, each Job takes over some CATEGORYIDs. Performs an Ignite cache-query (I paste it below), gathers the results, runs calculations on them, transforms them to other objects and saves them to some other smaller table in the Database. Finally it returns a success flag true/false. [13:29:09,520][WARN ][pub-#50%ppsp-cluster-IV%][IgniteH2Indexing] Query execution is too long [time=5007 ms, sql='SELECT "PPSP-IMDG-CACHE".SimulationInitialValues._KEY, "PPSP-IMDG-CACHE".SimulationInitialValues._VAL FROM "PPSP-IMDG-CACHE".SimulationInitialValues WHERE categoryId in ( 1, 2, 3, 4, 5, 6, 8 ) and geoChannelId in ( 3, 4, 5, 6 ) and type= 3 and week between 1888 and 1939', plan= SELECT "PPSP-IMDG-CACHE".SIMULATIONINITIALVALUES._KEY, "PPSP-IMDG-CACHE".SIMULATIONINITIALVALUES._VAL FROM "PPSP-IMDG-CACHE".SIMULATIONINITIALVALUES /* "PPSP-IMDG-CACHE"."type_idx": TYPE = 3 */ WHERE ((WEEK >= 1888) AND (WEEK <= 1939)) AND ((TYPE = 3) AND ((CATEGORYID IN(1, 2, 3, 4, 5, 6, 8)) AND (GEOCHANNELID IN(3, 4, 5, 6)))) , parameters=[]] Now, if I can align the CATEGORYIDs that each node has on its local cache with the CATEGORYIDs that it receives along with a Job execution, then the SQL query could be local-only. I have seen examples of affinityRun and affinityCompute buf these are for distributed closures only. I would like to do similar with ComputeTask approach because I need it in order to control other things as well.
