How much heap size can we increase?
The theoretical limit is 2^64 bytes, which is 16 exabytes (1 exabyte = 1024 petabytes, 1 petabyte = 1024 terabytes). However, most OS’s can’t handle that. For instance, Linux can only support 64 terabytes of data. Note: We don’t recommend you exceed 2 GB of in use JVM heap.
