Quick questions on Virtual Memory and Cache Memory Modes

A few quick questions:

   1. Are the cache memory modes: OFFHEAP_TIERED, OFFHEAP_VALUES, and
   ONHEAP_TIERED, deprecated in Ignite 2.1?
   2. In version 2.1, if I don't enable persistence store, do all data and
   indexes get stored on heap, possibly causing OME errors?
   3. Is the virtual memory used when persistence store is not enabled?

Thanks

1 & 2. Starting with 2.0 all data is stored in off-heap memory, regardless of
persistence configuration. Memory mode configuration is removed.
3. Yes. Data is always stored in pages which can transparently reside both
in memory and on disk. If persistence is not enabled, you have only
in-memory pages, but the data format is the same.
