Anything that a thread wrote before its Runnable exited is visible to the thread that executes join(). Anything that a thread wrote before executing start() will be visible to the spawned thread. Another thing to mention: volatile variables and synchronization have a function that's rarely menti...
It is used to provide a distributed configuration service, synchronization service, and naming registry for large distributed systems. ZooKeeper's architecture supports high availability through redundant services. Clients can thus ask another ZooKeeper leader if the first fa...
This document describes ZooKeeper, which is essentially a centralized service for distributed systems to a hierarchical key-value store. It is used to provide a distributed configuration service, synchronization service, and naming registry for large distributed systems....
Fork and join can be modeled in a similar manner using auxiliary synchronization variables. Each thread executes a sequence of atomic instructions in program order (determined by the control flow graph). During the execution, the scheduler picks a thread and executes the next atomic instruction in...
