" If you have primitive array fields – always use bulk methods to process them. ByteBuffer bulk methods performance is close to those of Unsafe (but ByteBuffer are always a little slower). "

GitHub - xerial/larray: Large off-heap arrays and mmap files for Scala and Java
LArray can create arrays with more than 2G(2^31) entries. 2^31 -1 (2G) is the limitation of the default Java/Scala array size, because these arrays use 32-bit signed integer (int) as indexes. LArray uses long type indexes of 64-bit signed integers to resolve this limitation. For example, the entire human genome data (3GB) can be stored in LArray. LArray can be released immediately from the memory.

" A library for managing large off-heap arrays that can hold more than 2G (2^31) entries in Java and Scala. Notably LArray is disposable by calling LArray.free or you can let GC automatically release the memory. LArray can be used to create an mmap (memory-mapped file) whose size is more than 2GB. "
