Hello, Igniters. Why test on TC can allocate Data Region bigger than the amount of available RAM? How can I disable this feature in a specific test?
"memoryAllocated=1024.0 GiB ... required=1093413MB, available=96675MB" I have a test [1] that try to create Data Region of 1024 Gib size. I want to check OOM exception that should occur while this DataRegion starting. Locally, I have it. But, On TC that DataRegion successfully created [2] I see following log messages: ``` [2019-04-13 21:31:30,426][INFO ][exchange-worker-#91818%test-server%][PageMemoryImpl] Started page memory [memoryAllocated=1024.0 GiB, pages=260204016, tableSize=19.8 GiB, checkpointBuffer=2.0 GiB] ....
