Concurrent counter are part of almost every system, it is used to collect data, thread synchronization etc. Java has good support of heap based counter. There could be use case when you need counter that can be shared between processor. How to build inter process countersDatabaseThis is first option that comes to mind, database sequence is counter that can be used by multiple process. All concurre
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.
