Hi, I have a 4 server node cluster with caches are on heap.
Whenever i try to get keys using a scan query or sql field query the heap usage increases drastically and drops down in few minutes as if both the queries are loading all respective cache entries as copies in response to the keys only request. A get all keys request when cluster is under load with significant heap usage would crash the nodes with OOM. Is there any other efficient way to get all keys other than scan query that iterates over cache entries or sql query? How best to estimate the heap size requirement for handling get all keys type requests.? Is there any community project for reading and displaying cache entries other than the old ignite web console? Thanks Dina
