Hi Denis, thanks for answering. That completely cleared out my doubt. I would like to know one more thing. I was testing with ~10000000 (10 million) records with each records of ~1400 bytes. When I was trying to keep everything on-heap I had to allocate around 15GB to on-heap to store all these records. But when I switched off on-heap and kept everything off-heap, same number of records got fit in 10 GB off heap memory region. Does it imply that when ignite saves in on-heap it's in deserialized form hence exact memory(no. of records * size of one record) is required. But when it keeps in off-heap it is stored in serialized form hence less memory than expected is required. Or is there some other reason for this memory requirement difference.
