HI Let me rephrase my question, guess I have conveyed my question correctly.
Lets take an example Ignite cluster with backing store as RDBMS - oracle and no eviction in place. As we all know, we can run complex queries on Oracle to retrieve desired data. In this case also, since we dont have eviction in place, all the time data is retrieved from RAM only, the only time request goes to Oracle is for Upserts and delete. So if oracle DB is loaded heavily while running these queries also, it does not affect the cluster performance when it comes to data retrievals, am i right ?? Inserts/Update/Deletes on DB may get slower if DB is loaded with these heavy queries. Similar way, how can we achieve this with ignite cluster with native persistence ? When native persistence is used, if we run some heavy queries on cluster thru SQLLINE, it may give out of memory error and node might crash also. How can we avoid this, it should run on backing store, I am fine if thge query exection takes longer time, but cluster should not get crashed. Hope I conveyed my requirements more clear this time.
